Synthesis of a LiZnSc(MoO4)3:Eu3+-Based Red Phosphor

Аннотация

Abstract—Phase relations in the Li₂MoO₄–ZnMoO₄–Sc₂(MoO₄)₃ system have been studied by X-ray diffraction and differential thermal analysis. We have synthesized the ternary molybdate LiZnSc(MoO₄)₃, which crystallizes in triclinic symmetry (sp. gr. \(P\bar {1}\)). A continuous series of solid solutions with an orthorhombic structure (sp. gr. Pnma) has been shown to exist on the Li₂Zn₂(MoO₄)₃–Li₃Sc(MoO₄)₃ join. A luminescent material based on the ternary molybdate doped with europium ions, LiZnSc(MoO₄)₃:Eu³⁺, has been prepared by solid-state reaction, and its photoluminescence (excitation and emission) spectra have been measured.
