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.
