ZnAl2O4 thin film, UV emission, Cathodoluminescence, Electron beam penetration depth

ZnAl2O4 thin films for deep UV emitting phosphor were prepared by thermal diffusion of ZnO and a-sapphire substrate at 1000 oC. From analysis of UV emission intensity by cathodoluminescence and penetration depth, it is considered that emiting layer of 650 nm was formed.
