Abstract
The red emitting phosphors for low voltage cathode luminescent, fine $(Y,Gd)_2O_2$S : Eu powders were synthesized and investigated the effect of $Gd^{3+}$as sensitizer at variety of sintering temperature. The highly intense emission line of $(Y,Gd)_2O_2$S : Eu at 627 nm is attributed in the transition from $^5D_o to ^7F_2$ energy levels. It showed the maximum value at the doping level of 5 mole% of $Gd^{3+}$at $950^{\circ}C$ of sintering temperature and then, it was degraded rapidly. The mean particle size of $(Y,Gd)_2O_2$S : Eu was obtained around 1 fm and the cathode luminescent properties of (Y,Gd)$_2$O$_2$S : Eu were better than those of $(Y,Gd)_2O_2$S : Eu.
