Abstract
The d-d luminescence of Ti3+ ions was first observed in the double Ti/SiO2 system at room temperature. Silica glass doped with titanium was synthesise d in a steady-state laser plume. The luminescent state was obtained by prod ucing oxygen-deficient centres in the chemical reaction between Ti and SiO2 . Comparison of the luminescence and absorption spectra of the titanium-dop ed silica glass with the spectra of a Ti3+:Al2O3 crystal suggests that the 690-nm luminescence band belongs to Ti3+ ions.
