摘要：

Nominally undoped ZnO ceramics were sintered in air and N-2 flow at 1000 degrees C. Room temperature photoluminescence (PL) spectra of the samples were measured and analyzed using Gaussian fitting. The self-activated orange PL band peaking at 610 nm was separated by Gaussian deconvolution. Based on the obtained results compared with some literature data, it has been concluded that the defects responsible for self-activated orange emission in ZnO are zinc vacancies.
