摘要：

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. (C) 1999 Elsevier Science S.A. All rights reserved.
