Abstract

In order to enhance discharge efficiency of Plasma Display Panel (PDP), we used an electride as electron emission layer for PDP during PDP discharge process. As the electride used in this study, $12CaO7Al_2O_3$, has low work function, it is expected to yield high electron emission during glow discharge process. $12CaO7Al_2O_3$ powder was synthesized from $CaCO_3$ and $Al(OH)_3$ powder and Ca treated for realization of electride characteristics. The $12CaO7Al_2O_3$ powder was coated on the surface of dielectric layer of PDP and discharge characteristics of electride material were evaluated.
