Popis:	A comparative study of cathodoluminescence and thermoluminescence of MgO and MgO:Ca single crystals at temperatures 3.9–295 K has been performed. The results strongly support that shallow hole trapping centres in the form of [Ca]+ (Ca2+O– complexes) are created in MgO:Ca under irradiation. These centres decay thermally at 58 K. The 6.8 eV emission, observable in MgO, especially in Ca-doped MgO crystals, is caused by the recombination of electrons with the holes localised in these centres. (© 2005 WILEY-VCH Verlag GmbH & Co.
