Abstract

The luminescence properties of Eu³⁺, Tb³⁺ and Tm³⁺ in strontium-lanthanum gallate, SrLaGa₃O₇, solid solutions were systematically examined. The emission intensity of Eu³⁺, Tb³⁺ have maxima at x=0.8 of SrLa_1-xR_xGa₃O₇ (R=Eu³⁺, Tb³⁺) under UV excitation and the activator concentration dependencies of the emission intensity are unique. The mechanism of concentration dependence is discussed by the crystal structure and the energy migration.
