Herein, the photoluminescence (PL) and thermoluminescence (TL) properties of rare earth doped cubic double perovskite tungstate Ba_2(1−x)(Na,RE)_xZnWO₆ (RE = Ce³⁺, Eu³⁺ and Dy³⁺) phosphors synthesized by the solid‐state reaction method are presented. The self‐luminescence of pure Ba₂ZnWO₆ material in the blue‐green region is enhanced by Ce³⁺ doping with its most effective concentration of 3 mol%. The dominant emission in orange (of Eu³⁺ at 597 nm) and blue (of Dy³⁺ at 485 nm) region in the emission spectra of Ba_2(1−x)(Na,Eu)_xZnWO₆ and Ba_2(1−x)(Na,Dy)_xZnWO₆ phosphor, respectively, shows highest intensity for 3 mol% of Eu³⁺ and 2 mol% of Dy³⁺ ion in the host lattice. The broad excitation band of Ce³⁺ and Dy³⁺ doped phosphor in the near UV region claims its candidature for solid‐state lighting. TL studies are also performed using γ‐radiation. Pure host material shows a simple glow curve while the rare earth ion doped phosphor shows a complex glow curve with enhanced intensity. Phosphor shows the fairly linear response up to 1 kGy radiation. Glow curves are deconvoluted and the trap parameters are calculated by Chen's peak shape method.

稀土掺杂立方双钙钛矿钨酸盐Ba2（1-x）（Na，RE）xZnWO6（RE = Ce3 +，Eu3 +和Dy3 +）荧光粉的发光特性

此处，稀土掺杂立方双钙钛矿钨酸盐Ba _{2（1- x）}（Na，RE）_x ZnWO ₆（RE = Ce ³⁺，Eu ³⁺和Dy ³⁺）的光致发光（PL）和热致发光（TL）特性）提出了通过固态反应方法合成的磷光体。Ce ³⁺掺杂可增强蓝绿色区域中纯Ba ₂ ZnWO ₆材料的自发光，其最有效浓度为3 mol％。Ba _2（1-）的发射光谱中的橙色（Eu ³⁺在597 nm处）和蓝色（Dy ³⁺在485 nm处）区域中的主要发射_x）（Na，Eu） _x ZnWO ₆和Ba _{2（1- x）}（Na，Dy） _x ZnWO ₆荧光粉分别显示3 mol％Eu ³⁺和2 mol％Dy ³⁺离子的最高强度在宿主晶格中。Ce ³⁺和Dy ³⁺的宽激发带在近紫外线区域中掺杂的磷光体声称其对固态照明的候选资格。TL研究也使用γ辐射进行。纯主体材料显示简单的辉光曲线，而稀土离子掺杂的磷光体显示强度增强的复杂辉光曲线。荧光粉显示出高达1 kGy辐射的线性响应。对辉光曲线进行反褶积，并使用Chen的峰形方法计算陷阱参数。
