Abstract

Ce-doped yttrium aluminum gallium garnet (YAGG:Ce) as a green-emitting phosphor was synthesized by solid state reaction. Its photoluminescence properties under vacuum UV excitation were investigated. The crystalline phase of Al2O3 and the use of fluxing agents affected the luminescence characteristics of the YAGG:Ce phosphors. Especially, the nano-sized γ-Al2O3 as an Al source increased the emission intensity. Also, the combination of α-Al2O3 - BaF2 and γ-Al2O3 - AlF3 resulted in the improvement of luminance most effectively.
