Abstract :
Cathodoluminescent properties of ZnO-based phosphor powders were investigated. Zn-Y-O and Zn-Al-O powders showed near UV emission peaked around 400 nm and 270 nm, respectively under electron beam excitation. The CL intensity were increased linearly, it indicates that the phosphors were prepared uniformly and homogeneously. There are many possibility for new phosphors which showed UV emission for new applications.
