Developing effective analytical techniques for detecting amoxicillin and fenobucarb residues, primary components of antibiotics and pesticides with sustantial health and environmental impacts, remains challenging. Surface-Enhanced Raman Scattering (SERS) is a rapid, simple, and highly sensitive analytical method with the potential integration into compact, handheld devices for real-time, on-site monitoring. In this work, Ag–Au alloy nanoparticles for SERS-based sensor materials with uniform structures, tunable composition, and adjustable plasmon resonance bands are proposed. The findings show that a silver fraction of 0.8 is optimal for detecting amoxicillin and fenobucarb by SERS, attributable to the synergistic effects of enhanced Raman scattering capabilities of Ag and Au compared to their single-element counterparts. Density Functional Theory (DFT) calculations indicated that electron transfer occurs from the ligands to the clusters during adsorption, which is related to the SERS chemical enhancement mechanism. SERS spectra analysis and Mulliken charge calculations for metallic atoms illustrate the highest electron transfer from ligands to the Ag4Au2 bimetallic cluster, underscoring the superior enhancement capability of the alloyed surface compared to pure Ag6 and Au6 clusters. Our work offers an effective route to find suitable SERS substrate for each analyte.

We report on the distributed-feedback dye laser based on the polymeric multilayer structure and rhodamine 6G. The periodic structure of the one-dimensional photonic crystal was fabricated by spin coating technology and alternately stacking of high and low refractive-index polymers. One of the polymeric layers consists of nanoparticles to change the effective refractive index. The multilayer showed a photonic bandgap in the transmission spectrum and the surface-emitting laser output was obtained at the blue side band-edge under the excitation of the second harmonic of a Nd:YAG laser. Wavelength tuning of the laser peak was possible by changing the doping density of the nanoparticles.

Y3Al5O12:Cr3+ ceramics were prepared by a new method of electron beam synthesis. Special features of this method are the fast speed of synthesis, high phase purity and stoichiometry. The samples were characterized by SEM and XRD methods. After the samples structure was confirmed, the optical measurements of the excitation/emission spectra and luminescence kinetics were performed in a wide temperature range. Characteristic excitation and emission spectral features of the 6-fold coordinated Cr3+ ions were detected and investigated; their presence is solid proof of successful doping of the prepared ceramics samples with the trivalent chromium ions. The developed technique of ceramics synthesis can be applied to other samples with different chemical compositions.

In this work, we study the possibility the use of Nd3+, Yb3+:CeF3/CeO2 nanoparticles in ratiometric luminescence thermometry. In order to explain the mechanism of the luminescence temperature sensitivity, we physically characterized the samples by means of transmission electron microscopy (TEM), X-ray diffraction (XRD), laser spectroscopy, and electron paramagnetic resonance (EPR). In particular, Nd3+, Yb3+:CeF3 nanoparticles were synthesized via co-precipitation method and annealed in air at 600 °C for 0, 15, 30, 60, and 120 min to obtain double-phase Nd3+, Yb3+:CeF3/CeO2 nanoparticles as well as single-phase Nd3+, Yb3+:CeO2 ones (at 120 min). The physical diameter of the samples gradually increases from 19 ± 2 (doped CeF3) to 409 ± 18 nm (doped CeO2). It was suggested, that the double-phase samples consist of sintered doped CeF3 and CeO2 nanoparticles having average grain diameter around 65 nm. The single-phase CeO2 sample also consists of sintered CeO2 nanoparticles, suggestively. The luminescence intensity ratio (LIR) was analyzed in the 80–320 K range (LIR = INd/IYb, where 848–925 nm (4F3/2 – 4I9/2) Nd3+ and 925–1048 nm (2F5/2 – 2F7/2) Yb3+). The maximal relative temperature sensitivity was achieved for Nd3+, Yb3+:CeO2 sample (∼0.2 %/K), which is very competitive value. The LIR function has a simple linear temperature dependency in the broad 80–320 K which allows uniquely identifying the temperature at least in the studied broad temperature range. The mechanism of temperature sensitivity was suggested.

This study aimed to develop an optimal RPL material by adding impurities such as (Al₂O₃, Mn₂O₃, P, and Si) to CaSO₄ and evaluating the radiophotoluminescence (RPL) properties. Adding P to CaSO₄ was found to improve the RPL response significantly. The effect of P concentration on RPL properties were investigated, and it was found that the optimal P concentration was about 0.5 % and that excessive concentrations of P reduced the RPL response. The evaluation of defect species in CaSO₄ using ESR measurements showed a robust correlation between the RPL response and the E′ centers, with a significant increase in SO ₂-, PO₄2- and Al₂O₃ were also correlated with RPL. In high-dose irradiation, the RPL intensity and the spin density of defect species by ESR increased linearly to about 10 Gy and 1000 Gy (1 kGy), respectively, but saturation was observed above that level. This paper contributes to the optimization and characterization of CaSO₄ with P as an RPL material to make CaSO4 a more accurate RPL dosimeter.

In this study, cadmium sulfide (CdS) nanocrystals capped with 3-mercaptopropionic acid (MPA) were prepared and tested as nanoadsorbents and photocatalysts for the removal and degradation of reactive black 5 (RB5) dye in aqueous solutions. The dye adsorption data were collected at 298, 308, and 318 K. The modeling of experimental data showed the best fit to the Sips isotherm model, and the adsorption kinetics followed the pseudo-first order (PFO) model. CdS MPA had a specific surface area of 140 m2/g and 23.90 mg/g maximum adsorption capacity at 298 K, attaining a removal efficiency of 95.2 % after 20 min. The steric and energetic parameters were analyzed using statistical physics models. The experimental data was predicted using an advanced single-energy adsorption model. At low temperatures, dye adsorption occurred via physisorption with weak interactions, thereby establishing a monolayer adsorption process. The dye molecules were removed in parallel and non-parallel orientations. At high temperatures, the dye adsorption was multi-molecular, indicating that the dye could be removed at a slanted position. Theoretical calculations indicated that physical interactions were involved in RB5 adsorption. Photocatalytic studies indicated that the degradation efficiency was close to 99 % within 120 min, and that the PFO kinetic model best matched the experimental data. RB5 adsorption on the CdS-MPA adsorbent led to three degradation-regeneration cycles. These results highlight the effectiveness and sustainability of this system, reinforcing its feasibility and potential application in photocatalytic reactions for environmental depollution.

Common glass lacking spectral adjustment capabilities fails to deliver energy-saving benefits, while radiative cooling technology without visible transparency compromises lighting and aesthetic requirements. In response, we introduce a novel solution termed as radiative cooler. (GIRC). GIRC efficiently reduces temperature increases caused by sunlight by specifically blocking near-infrared (NIR) rays, allowing visible light to pass through, and dispersing heat via the atmospheric window. Amazingly, GIRC manages multi-band spectral control with a simplified three-layer design, avoiding complex manufacturing steps and offering potential for large-scale production. Spectral analysis underscores GIRC's efficacy, demonstrating a maximum transmittance of 92.3 %, an impressive visible transmittance of 89.61 %, an average near-infrared transmittance of 51.89 %, and an emissivity of 94.70 % within the atmospheric window. The effectiveness of GIRC in cooling multi-crystalline silicon solar cells is demonstrated by a peak temperature drop of 9.1 °C, an average reduction of 5.12 °C, and a 3 % boost in solar cell efficiency over traditional glass alternatives. Indoor resistance assessments further attest to GIRC's cooling prowess, exhibiting a consistent temperature reduction of ∼7 °C relative to common glass, thus rendering it suitable for internal circuitry cooling applications. Energy consumption analysis underscores GIRC's significant efficiency gains, estimating a potential 17 % reduction in annual cooling energy consumption, compared to common glass configurations. The proposed GIRC glass not only moderates daytime temperatures but also preserves transparency and aesthetic appeal, thus holding immense promise for enhancing the thermal management of optoelectronic equipment in building structures.

Increasing the damage threshold of gold-coated pulse compression gratings is crucial for advancing petawatt-class laser systems considering the current low threshold of gold-coated photoresist gratings (GPGs). Various factors that influence the threshold of GPGs have been explored, but scant attention has been paid to the melting dynamics of the layers beneath the gold film. This study presents multi-layer gold-coated fused silica gratings (MGFSGs) that consist of a gold film, a chromium interlayer, and fused silica grating, wherein the interlayer functions as a heat sink. Ablation experiments were conducted using a femtosecond laser (800 nm, fs) at varying laser fluences, followed by the resultant laser damage morphology analysis. Dynamic descriptions of the laser absorption and temperature evolution in the lattice at various layers were facilitated using a two-temperature model that considered the boundary conditions of heat transfer at different material interfaces. Theoretical analysis and experimental observations revealed that a chromium interlayer can enhance the grating’s threshold. MGFSGs exhibit the capability to enhance the beam-normal damage threshold of the grating to 0.41 2, i.e., approximately 40% higher than the baseline of 0.29 2 for GPGs. These results offer pivotal insights for improving the damage resistance of gold-coated gratings.

A series of diphosphine Re(I) complexes Re(PPh3)(P-bpy), Re(PPh3)(P-terpy), Re(P-OEG)(P-bpy) and Re(P-OEG)(P-terpy) have been designed via decoration of the archetypal {Re(CO)2(NN-OEG)} core with the phosphine ligands bearing bipyridyl (P-bpy) and terpyridyl (P-terpy) functions, which are capable to bind Cu(I) and Cu(II) ions. The presence of the bipyridyl (NN-OEG) and the phosphine (P-OEG) ligands functionalized with oligo(ethylene glycol) fragments is sufficient to impart water-solubility to the target complexes Re(P-OEG)(P-bpy) and Re(P-OEG)(P-terpy) that makes possible to study their photophysical characteristics both in organic and aqueous media. The obtained complexes demonstrate phosphorescence from 3MLCT excited state typical for this type of chromophores and display weak sensitivity to molecular oxygen in methanol, which becomes almost negligible in aqueous and model physiological media. Addition of copper ions (Cu+ and Cu2+) to the solutions of Re(PPh3)(P-bpy), Re(PPh3)(P-terpy), Re(P-OEG)(P-bpy) and Re(P-OEG)(P-terpy) results in a dramatic decrease in their emission intensity accompanied by strong reduction of the excited state lifetime, while the other biologically relevant ions do not display a distinct effect onto the photophysical characteristics of the chromophores. The complexes response onto variations in the copper ions concentration was quantified by building up the lifetime-concentration calibration curves. To gain a deeper understanding of the sensing processes, DFT calculations were performed, which showed the substantial involvement of the orbitals of {(P-bpy/terpy)Cu} fragment into formation of the emissive excited states. Cellular experiments with Chinese hamster ovary (CHO–K1) cells demonstrate cytoplasmic localization of the PPh3-containing Re(I) probes.

A series of microcrystalline NaYF4 nanoparticles doped with Yb and Er were synthesized, and their Stokes and anti-Stokes emission was studied. Its temperature dependence made it possible to obtain high-temperature luminescent thermometry materials. The prospects of both Stokes and anti-Stokes luminescence for luminescent thermometry were studied and discussed.
