Abstract
The thermoluminescence of several Al2O3 samples doped with different i mpurities (mainly Cr and Ni) is studied. The main characteristics (emi ssion spectra, dose dependence, peak parameters) of the observed therm oluminescence glow curve are determined. A very high peak is found at 335 degrees C for some concentrations of Ni. The possible use of this material for dosimetry applications is discussed.
