Время-разрешенная люминесценция YAG:Сe3+,Tb3+ люминофоров

Abstract

The Ce3+, Tb3+ doped yttrium aluminum garnet phosphors were synthesized by high-tem-perature solid-state reaction method under reducing atmosphere. The preparation with this method requires repeated cycles of heating processes at high temperature up to 1600 °C to reinforce the interdiffusion and achieve a uniform single phase and homogeneity of the alloy. The luminescence properties of YAG:Ce3+,Tb3+ under excitation with a pulsed electron beam in nano- and millisecond time ranges were studied. The nature of luminescence centers of phosphors under radiation-induced influence is discussed.
