Luminescence Properties of Eu3+-Doped K1 – xMg1 – xSc(Lu)1 + x(MoO4)3 (0 ≤ x ≤ 0.5) Solid Solutions

Abstract

K_{1 – x}Mg_{1 – x}Sc(Lu)_{1 + x}(MoO₄)₃ (0 ≤ x ≤ 0.5) solid solutions have been prepared by solid-state reactions. The synthesized phases of variable composition have been characterized by X-ray diffraction and differential thermal analysis, and their luminescence excitation and luminescence spectra have been obtained. We have measured their spectroscopic and luminescent characteristics (luminescence excitation spectra, short- and long-lived photoluminescence spectra, and long-lived emission lifetime).
