摘要

Ce-doped yttrium aluminum gallium garnet (Y_3(Al,Ga)_5O_(12):Ce~(3+), YAGG:Ce) phosphors with the control of stoichiometry were synthesized by solid-state method. Photoluminescence properties of stoichiometry-controlled YAGG:Ce phosphors were investigated under vacuum UV excitation of 147 nm. The luminance of YAGG:Ce phosphors with non-stoichiometric compositions were higher than that of stoichiometric phosphor.
