About self-activated orange emission in ZnO
Nominally undoped ZnO ceramics were sintered in air and N₂ flow at 1000 °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 obta...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Nominally undoped ZnO ceramics were sintered in air and N₂ flow at 1000 °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.
