We investigated the structural and luminescence characteristics of Ba₂YZrO₆:xGd (0.01 ≤ x ≤ 0.11) perovskite ceramic phosphors prepared by sol-gel with dominating cubic phase. The Fourier transform infrared (FT-IR) spectrum depicted various shoulders attributed to the functional groups present in the host matrix. The photoluminescence (PL) spectroscopy exhibited the emission at 315 nm under the excitation of 229 nm light, owing to the ${{}^{6}P}_{7/2}\to {{}^{8}S}_{7/2}$ transition. We also observed concentration quenching in the prepared phosphor. Further, the electron paramagnetic resonance (EPR) spectra recorded for the samples under room temperature discerning three main resonance signals with effective g-values 6.02, 2.45, and 1.32.

我们研究了以溶胶-凝胶为主的立方相制备的Ba ₂ YZrO ₆：xGd（0.01≤x≤0.11）钙钛矿型陶瓷荧光粉的结构和发光特性。傅立叶变换红外（FT-IR）光谱描绘了归属于基质中存在的官能团的各种肩峰。光致发光（PL）光谱显示在229 nm的光激发下在315 nm处有发射，这是由于${{}^{6}P}_{7/2}\to {{}^8\mathrm{小号}}_{7/2}$过渡。我们还观察到了制备的荧光粉中的浓度猝灭。此外，在室温下为样品记录的电子顺磁共振（EPR）光谱可识别三个主要共振信号，其有效g值为6.02、2.45和1.32。
