Abstract

By means of measurements of X-ray-induced luminescence, photoluminescence, optical absorption, and time-resolved spectroscopy, it is shown that all nominally pure corundum crystals examined by us contain chromium and titanium as an impurity. The photoinduced thermoluminescence of nominally pure corundum single crystals is due to the release of electrons from F centers and Ti³⁺ ions and holes from Cr³⁺ ions during illumination of the crystals with light. The limiting energies of photons that arouse a TL response are 5.5, 4.9, and 3.4 eV, respectively.
