Herein, the photoluminescence (PL) and thermoluminescence (TL) properties of rare earth doped cubic double perovskite tungstate Ba2(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 Ba2(1−x)(Na,Eu)xZnWO6 and Ba2(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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
