Abstract

Since P-ELD(powders type electroluminescent device) phenomena were found by G.Destriau at first In 1936, lots of studying was performed in order to realize surface emission devices and flat panel display as a backlight. Due to the problem of low luminance and color and so on, it was delayed. Recently using electric field and thermal effect which can change it\`s molecular arrangement, it can be developed using photoelectric properties of P-ELD. P-ELD in this study was prepared by casting method. Basic structure is ITO/Phosphor/insulator/Al sheet, each layer was mixed by binder, which concentration 11p(poise) for phosphor, 8p(poise) fort insulator. Dielectric properties was investigated first and emission properties of P-ELD based on ZnS:Mn,Cu/ZnS:Cu,Br mixture. P-ELD prepared in this work exhibits about 100cd/㎡ 1-kHz simusoidal excitation.
