Effect of point defects on luminescence characteristics of ZnO ceramics

Photo- and thermally stimulated luminescence of ZnO ceramics are produced by uniaxial hot pressing. The luminescence spectra of ceramics contain a wide band with a maximum at 500 nm, for which oxygen vacancies V O are responsible, and a narrow band with a maximum at 385 nm, which is of exciton natur...
