Abstract
In order to investigate optical properties of single micron-sized ZnO particles embedded in alkali halide (KCl) crystal, cathodoluminescence (CL) measurements at liquid helium temperature have been performed. In contrast to the case for pellet of ZnO powder, CL spectra of the single ZnO particles exhibit intense ultraviolet (UV) luminescence and no green emission due to oxygen vacancies, which ensures higher quality of the ZnO particles in the KCl crystal compared with that of the ZnO powder. The CL images of the single particles reveal several bright spots. The results indicate that radiative recombination of the excitons effectively occurs at specific areas in the surface of the single particle.
