摘要
The present invention relates to a multiple rare earth co-activated long-afterglow luminescent material having its general chemical composition depicted by a formula aMO.bAl2O3.cSiO2.dGa2O3:xEu.yB.zN, wherein a, b, c, d, x, y, and z are coefficients with the ranges of 0.5≦a≦2, 0.5≦b≦3, 0.001≦c≦1, 0.0001≦d≦1, 0.0001≦x≦1, 0.0001≦y≦1, 0.0001≦z≦1, M is Ca or Sr, N is Dy or Nd, wherein Sr (or Ca), Al, Si, Ga are main matrix elements and Eu, B, Dy (or Nd) elements are activators. The long-afterglow luminescent material according to the present invention has advantage of a longer persistence period and a water resistance greatly superior to known rare-earth activated aluminate long-afterglow luminescent materials.
