摘要	ZnO phosphor was synthesized by annealing ZnO powder at low 02 partial pressure and in vacuum. Zoo has two emissions, which are located at about 380 nm (UV emission) and 510 mn (green emission). The UV emission can be attributed to the exciton emission, which is a single-center process, whereas the green emission is related to native defects, such as V-o(.) and V-zn', which is a two-center (donor-acceptor) recombination process. The high-density excitation favors the UV emission, whereas the green emission likely appears in the samples annealed at low O-2 Partial pressure. It was shown that the energy transfer may occur from the UV emission center to the green emission center, and the exciton diffusion mechanism for the transfer was proposed.
