Abstract:

The influence of UV radiation at a high temperature on the luminescent properties of oxygen-deficient corundum was studied. Efficient photoconversion, F- ⇒ F+-centres, which leads to appearance of the 3.76 eV F^{centre emission in the main dosimetric TL peak and the 5.91 eV band in luminescence excitation spectra of this centre, was found. Correlation between the integral intensity of the TL peak in the 3.76 eV emission band and the intensity of the 5.91 eV excitation band was established. Probable mechanisms of the thermostimulated photoconversion and TL in the F+-centre emission band are discussed.}
