Cu-SSZ-13 zeolite is the leading commercial catalyst for NO_x purification on diesel vehicles. Although the synthesis via the one-pot method improves the preparation efficiency, the obtained Cu-SSZ-13 zeolites usually suffer from insufficient catalytic activity and limited hydrothermal stability. Our research demonstrates that doping with 0.3 wt% Y can significantly enhance both the selective catalytic reduction with NH₃ (NH₃-SCR) performances and hydrothermal stability of Cu-SSZ-13 catalysts synthesized via dual-template one-pot method. X-ray diffraction (XRD), Raman, and transmission electron microscopy-energy dispersive spectroscopy (TEM-EDS) analyses reveal that Y enters the zeolite framework during the crystallization process, promoting the generation of active [Cu(OH)]⁺-Z species. Meanwhile, nuclear magnetic resonance (NMR) and NH₃-temperature programmed desorption (NH₃-TPD) confirm that the addition of Y preserves the structures of framework and prevents the de-alumination against hydrothermal aging and thus enhances the stability of the Cu-SSZ-13. These findings offer valuable insights into optimizing SCR catalysts for the control of NO_x emission in diesel vehicles and highlight the expanded utility of rare earth metal Y in catalyst development.

Cu-SSZ-13沸石是用于柴油车辆氮氧化物净化的领先商用催化剂。虽然一锅法的合成提高了制备效率，但得到的Cu-SSZ-13分子筛催化活性不足，水热稳定性有限。我们的研究表明，在双模板一锅法合成的Cu-SSZ-13催化剂中，掺杂0.3 wt% Y可以显著提高催化剂的NH3选择性催化还原（NH3- scr）性能和水热稳定性。x射线衍射（XRD）、拉曼光谱（Raman）和透射电子显微镜-能谱（TEM-EDS）分析表明，Y在结晶过程中进入沸石骨架，促进了活性[Cu(OH)]+-Z物质的生成。同时，核磁共振（NMR）和nh3 -温度程序解吸（NH3-TPD）证实，Y的加入保留了骨架结构，阻止了水热老化脱铝，从而提高了Cu-SSZ-13的稳定性。这些发现为优化SCR催化剂以控制柴油车辆NOx排放提供了有价值的见解，并突出了稀土金属Y在催化剂开发中的广泛应用。

This study focuses on the synthesis and luminescence properties of Ce³⁺-doped CaSrSiO₄ phosphor. Typically, the synthesis of Ce³⁺ luminescent materials requires a reducing atmosphere. In this work, the traditional high-temperature solid-phase method was used in air atmosphere with SiC as the reducing material to successfully prepare CaSrSiO₄:Ce³⁺ blue phosphor, and the self-reduction mechanism is discussed. The samples were characterized by X-ray diffraction (XRD), Rietveld refined XRD, scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS), and the characterization results show that the CaSrSiO₄ phase is obtained. The resulting phosphor exhibits exceptional brightness in blue light and remarkable thermal stability, with a ratio of 94% at elevated temperatures (423 K/303 K). The Ca_1–xSr_1–xSiO₄:0.015Ce³⁺,0.015Li⁺ phosphors were combined with commercial green and red powders to create a white light-emitting diode (WLED) package with 365 nm chips. This results in a WLED with high performance, featuring a high color rendering index of Ra = 95 and a correlated color temperature (CCT) of 5373 K. At the same time, a visible light communication system was produced to test the communication bandwidth. Compared with commercial YAG:Ce³⁺ phosphor and BAM:Eu²⁺ phosphor, the bandwidth is increased by 40.9% and 1092.3%, respectively.

本文主要研究了Ce3+掺杂CaSrSiO4荧光粉的合成及其发光性能。通常，Ce3+发光材料的合成需要还原气氛。本文采用传统的高温固相法，以SiC为还原剂，在空气气氛下成功制备了CaSrSiO4:Ce3+蓝色荧光粉，并对其自还原机理进行了探讨。采用x射线衍射（XRD）、Rietveld细化XRD、扫描电镜（SEM）和x射线光电子能谱（XPS）对样品进行了表征，表征结果表明得到了CaSrSiO4相。所得的荧光粉在蓝光下表现出优异的亮度和出色的热稳定性，在高温（423 K/303 K）下的比例为94%。将Ca1-xSr1-xSiO4:0.015Ce3 +，0.015Li+荧光粉与商用绿色和红色粉末结合，制成了365 nm芯片的白色发光二极管（WLED）封装。这使得WLED具有高性能，具有Ra = 95的高显色指数和5373 K的相关色温（CCT）。同时，制作了一个可见光通信系统来测试通信带宽。与商用YAG:Ce3+荧光粉和BAM:Eu2+荧光粉相比，带宽分别提高40.9%和1092.3%。

In this study, a double-perovskite phosphor SrLaNaTeO₆:5% Sm³⁺, 0.8% Mn⁴⁺ was successfully synthesized via a molten salt method. A novel dual-mode optical thermometer is proposed, using the fluorescence intensity ratio (FIR) between Sm³⁺ and Mn⁴⁺, along with the decay lifetime of Mn⁴⁺ emission as temperature readouts, to investigate its temperature sensing properties in the range of 303–493 K. Crystal structure analysis indicates that Sm³⁺/Mn⁴⁺ co-doped SrLaNaTeO₆ possesses cubic symmetry, belonging to the Fm-3m (225) space group. The oxidation states of Mn⁴⁺ and Te⁶⁺ in the doped phosphors were further confirmed by electron paramagnetic resonance (EPR) spectra and X-ray photoelectron spectroscopy (XPS). The synthesized SrLaNaTeO₆:5% Sm³⁺, 0.8% Mn⁴⁺ phosphor exhibits excellent temperature sensing performance, with an optimal relative sensitivity (S_R) of 2.38%/K at 463 K using the FIR (I(⁴G_5/2 → ⁶H_5/2)/I(²E_g→⁴A_2g)) method. Additionally, a maximum S_R of 1.27%/K is achieved at 493 K using the fluorescence decay lifetime of the ²E_g (Mn⁴⁺) excited state. This novel fluorescent material demonstrates its potential for application in dual-mode optical temperature sensors with an expanded temperature range and enhanced sensitivity.

本研究通过熔盐法成功合成了双钙钛矿型荧光粉SrLaNaTeO6:5% Sm3+， 0.8% Mn4+。提出了一种新型的双模光学温度计，利用Sm3+和Mn4+之间的荧光强度比（FIR）以及Mn4+发射的衰减寿命作为温度读数，研究了其在303-493 K范围内的温度传感性能。晶体结构分析表明，Sm3+/Mn4+共掺杂的SrLaNaTeO6具有立方对称性，属于Fm-3m（225）空间群。通过电子顺磁共振（EPR）和x射线光电子能谱（XPS）进一步证实了掺杂荧光粉中Mn4+和Te6+的氧化态。采用FIR (I（4G5/2→6h55 /2)/I(2Eg→4A2g)）方法合成的SrLaNaTeO6:5% Sm3+， 0.8% Mn4+荧光粉具有优异的感温性能，在463 K时的最佳相对灵敏度（SR）为2.38%/K。此外，利用2Eg （Mn4+）激发态的荧光衰减寿命，在493 K时获得了1.27%/K的最大SR。这种新型荧光材料具有扩展温度范围和增强灵敏度的双模光学温度传感器的应用潜力。

Chiral lanthanide complexes exhibit high circularly polarized luminescence (CPL) activity due to magnetic dipole-allowed Ln-centered f–f transitions. However, the solution-state CPL activity of these complexes is often compromised upon film formation due to disordered molecular packing. To address this, we designed the enantiopure chiral β-diketonate ligand L₁^S, incorporating long alkyl chains. CPL analysis reveals that (NMe₄)[Eu(L₁^S)₄] retains its high CPL activity in the film state, comparable to that observed in solution. In contrast, (NMe₄)[Eu(L₂^S)₄], lacking alkyl chain modification, shows a significant decrease in the luminescence dissymmetry factor (g_lum), from −0.28 in solution to −0.01 in the spin-coated film. This result demonstrates the role of alkyl–alkyl interactions in impacting the molecule stacking, coordination configuration and the resulting CPL activity. This work provides an alternative for regulating CPL activity of spin-coated film of lanthanide complexes.

手性镧系配合物由于具有磁偶极允许的以镧为中心的f-f跃迁而表现出较高的圆极化发光活性。然而，这些配合物的溶液态CPL活性往往在膜形成时由于无序的分子堆积而受到损害。为了解决这个问题，我们设计了包含长烷基链的对映纯手性β-二酮酸酯配体L1S。CPL分析表明，（NMe4）[Eu(L1S)4]在膜态下保持了较高的CPL活性，与溶液中观察到的CPL活性相当。相比之下，（NMe4）[Eu(L2S)4]由于没有烷基链修饰，其发光不对称系数（glum）显著降低，从溶液中的−0.28降至自旋镀膜中的−0.01。这一结果证明了烷基-烷基相互作用对分子堆积、配位构型和CPL活性的影响。本研究为调控镧系络合物自旋涂覆膜的CPL活性提供了一种新的方法。
