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 SrLa1-xRxGa3O7 (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.
