| Abstract: | Summary Samples of α-alumina prepared at low temperature by means of a special procedure are investigated by recording their thermoluminescent emissionvs. temperature and wavelength. Taking into account the effect of thermal treatments, evidence is obtained for the presence of a distribution of electron traps of different depths. Arguments are advanced for characterizing the nature of the lattice defects originating these traps. |
