Abstract:

We have studied the effect of bombardment by Cu+ and Ti + ions with energy 30 keV on the optical absorption and luminescence of F centers in oxygen-deficient aluminum oxide. We have shown that in the induced optical absorption spectra there are six components of gaussian shape, which can be assigned to absorption bands of F+, F2, and F 2 + centers. We have established that bombardment of the samples by ion beams has a weak effect on the thermoluminescence parameters in the 3.0 eV and 2.4 eV bands, while in the 3.8 eV luminescence band for F + centers, the thermoluminescent response increases considerably. © 2008 Springer Science+Business Media, Inc.
