Abstract

Zn/sub 2-x/Mn/sub x/SiO/sub 4/ phosphors for PDP were synthesized by solid state reaction method. The effects of firing temperature, ratio of hydrogen gas to nitrogen for heat treatment and concentration of activator and co-dopants on the luminous properties have been investigated. It was found that the phosphor fabricated at 1400℃ with x = 0.002 Mn concentration had a maximum brightness. Luminous properties of a phosphor were improved when Cr/sup 3＋/ was added as a co-dopant rather than other co-dopants.

PDP(Plasma Display Panel)에 적용하고자 하는 녹색 형광체 Zn/sub 2-x/Mn/sub x/SiO/sub 4/를 고상반응법으로 제작하였다. 소성온도, 열처리분위기의 수소와 질소가스의 비 그리고 Mn의 첨가제 및 co-dopant가 형광체의 특성에 미치는 영향에 대하여 관찰하였다. Mn의 농도 x=0.002로 하여 소성온도 1400℃에서 발광특성이 가장 우수하였고, co-dopant의 영향에서는 Cr/sup 3＋/를 첨가하였을 때 다른 첨가제를 사용하였을 때 보다 발광특성이 향상되는 것이 관찰되었다.
