Abstract: Using spectral-luminescent methods upon excitation by synchrotron radiation, structural defects caused by oxygen vacancies were revealed in ZrO$_2$–Y$_2$O$_3$–Ho$_2$O$_3$, ZrO$_2$–Y$_2$O$_3$–Er$_2$O$_3$, ZrO$_2$–Y$_2$O$_3$ crystals. The positions of the energy levels of oxygen vacancies V$^{+1}$ and V$^{+2}$ located near the conduction band are determined.

Keywords: zirconium dioxide, rare earth ion, oxygen vacancy, luminescence spectra, excitation spectra, synchrotron radiation.
