... enhancement of UV emission as well as effective suppression of native defect emission in ZnO upon the formation of BeO shell. Furthermore, a b lue- shift of ZnO near band edge (NBE) emission was observed ... conduction band minimum of BeO is of higher energy than that of ZnO [32]. In such case, a potential well for both electron and hole is formed and the exciton is confin...
