Structural analyses have been conducted using XRD and Rietveld refinement. The irregular shapes with porous morphology of nanocomposites captured by the FESEM and HRTEM studies and the presence of Zn, La, Al, and O elements have been confirmed by EDX spectroscopy. DRS technique corroborated bandgap values that lie in the range of 6.09–2.93 eV, while PL studies confirm a suppressed charge carrier recombination with increased concentrations of ZnO in the nanocomposite. The negative surface potential has been assessed by the Zeta analyzer, which indicates its suitability for the degradation of cationic dyes such as Rhodamine-B (RhB). The photocatalytic activity of LAZO nanocomposites in degrading RhB dye is significantly higher than that of pure ZnO and LAO under UV irradiation. Among the samples, LAZO (1:5) has the highest efficiency (∼97 %) in degrading RhB dye within 100 min. The effect of pH on the reaction medium and the role of reactive oxygen species were also examined. In the neutral medium, almost complete degradation of dye is achieved in 100 min. Radical trap experiments reveal that holes are the main oxidative species part in the degradation of RhB dye. The adsorption kinetic are best described by Pseudo second order kinetic model. Type I heterojunction charge transfer mechanism well explains the degradation pathway of RhB dye. The development of nanocomposite photocatalysts that facilitate efficient charge transfer mechanisms is a promising strategy for improving photocatalytic activity and removing organic contaminants from water sources.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"334 ","pages":"Article 130500"},"PeriodicalIF":4.3,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143293585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermoluminescence (TL) properties of un-doped and β-CSO:Pr³⁺ phosphors are evaluated under γ-irradiation doses ranging from 0.01 Gy to 5 kGy. The TL glow curves of β-CSO:3Pr³⁺ phosphors exhibited prominent peaks at 400 K and 550 K. Activation energy values, determined using CGCD and Chen's peak methods, ranged from 0.5 to 2.5 eV. The incorporation of Pr³⁺ ions introduced deeper traps and significantly enhanced the material's thermal stability. TL reusability measurements showed a standard deviation of less than 5 %, demonstrating consistent and reliable performance over multiple cycles. Deconvolution of the TL glow curves identified six distinct peaks in the un-doped sample, while the Pr³⁺ doped sample displayed a more intricate trap structure with four peaks, indicating the introduction of new or modified trapping sites due to Pr³⁺ doping. The Figure of Merit (FOM) values derived from the deconvolution analysis are all below 1.58 %, signifying an excellent fit between the observed and modelled TL signals.

However, the physicochemical interactions between them remain to be explored. This study conducted theoretical calculations and <em>in situ</em> X-ray diffraction (XRD) experiments to investigated these interactions, particularly for the conformational transition of the hybrid crystal. The results showed that the presence of TAGP would constrain the conformation and arrangement of HMX molecules. Bond length analysis indicated that the TAGP intercalation can shorten N–N bond lengths of HMX, which effectively suppresses the thermal decomposition initiated by the rupture of N–NO₂. The <em>In situ</em> XRD simulations and experiments confirmed the improvement in thermal stability of qy-HMX in comparison to the raw <em>β</em>-HMX, raising by stronger resistance to polycrystalline transitions of qy-HMX. The enhanced stability was attributed to the constraining effect of TAGP, forcing HMX molecules to maintain a ‘boat-chair’ conformation. Once constraint with TAGP formed, the ‘boat-chair’ conformation can exist stably even at room temperature, resulting in remarkable thermal stability of qy-HMX. Besides, electronic density of states calculations suggested that the intercalation of TAGP may decrease the number of electronic states in qy-HMX crystals near the Fermi level, contributing to the thermal stability improvement. In addition, further analysis on the interaction mode between HMX and TAGP molecules confirmed the presence of hydron bond and <em>van der Waals</em> interactions, which should be responsible for the stabilization of hybrid qy-HMX crystals.
