PHOSPHOR MIXTURE AND PLASMA DISPLAY PANEL COMPRISING THE PHOSPHOR MIXTURE

摘要

Phosphor mixtures for phosphor layers of plasma display devices are provided. The phosphor mixture includes a first compound selected from compounds represented by Gd1-yTbyAl3(BO3)4 (0.05<=Y<=0.8) and compounds represented by YBO3:Tb3+, and a second compound represented by Zn(Ga1-XAlx)2O4:Mn2+ (0.2<=X<=0.8). The first compound and second compound are mixed in a weight ratio ranging from about 3:7 to about 6:4. The inventive phosphor mixtures exhibit reduced decay times, thereby increasing color reproducibility and improving brightness characteristics.
