Structure and luminescence properties of Dy³⁺ doped quaternary tungstate Li₃Ba₂Gd₃(WO₄)₈ for application in wLEDs.

ABSTRACT: Quaternary tungstates with the composition Li₃Ba₂Gd₃(WO₄)₈ doped with different concentrations of Dy³⁺ (from 0.5 to 10 at%) were prepared by the solid-state reaction method at 900 °C. Their structural, spectroscopic and optical properties were studied systematically in this work. X-ray diffraction analysis confirmed the crystallization of Li₃Ba₂Gd₃(WO₄)₈ to have a monoclinic structure (sp. gr. C2/c); the lattice constants for 1 at% doping concentration of Dy³⁺ are a = 5.2126(2) Å, b = 12.7382(1) Å, c = 19.1884(3) Å, V_calc = 1273,40(4) ų and β = a × c = 91.890(9)°. The first p
