Abstract:
The photoluminescence excitation and steady-state photoluminescence spectra of nonstoichiometric zirconium oxide films with a high concentration of oxygen vacancies have been investigated. A band with energy of about 2.7 eV in the blue spectral region dominates in photoluminescence spectra of prepared films. The photoluminescence intensity of this band increases as the depletion of zirconium oxide films with oxygen increases. The excitation maximum of the blue photoluminescence band corresponds to energy of 5.2 eV. It has been established by quantum-chemical modeling that the optical absorption peak of the oxygen vacancy in crystalline zirconium oxide is located at energy of 5.1 eV. The analysis of the results has demonstrated that the blue photoluminescence band at 2.7 eV with the excitation peak near 5.2 eV is caused by oxygen vacancies in zirconium oxide.
