In this study, we examined the luminescence response of Ti-doped crystals to high-energy vacuum ultraviolet (UV) excitation. In addition to the thoroughly studied emission band of in the near-infrared region and blue emission at , we detected a UV emission band at . The excitation spectra of all emission bands were measured over the spectral range. Our results indicate that intrinsic anion defects are involved in the process of the excitation of the emission assigned to the charge transfer transitions . Analysis of the spectral and decay characteristics of the UV emission enables us to suggest that this band is associated with radiative decay of excitons localized at Ti ions.
