Description
The recently discovered high-intensity thermoluminescence (TL) emission in Al2O3 doped with Cr and Ni is analysed more deeply by measuring the effects of x-ray irradiation on the optical absorption in parallel with the TL process, together with the effect of optical bleaching. It is proposed that the high-intensity peak is due to oxygen vacancies, induced by the presence of Ni. The main recombination centre is Cr. (Author)
