Numerical analysis of simultaneous TL/TSC measurements.
Thermoluminescence (TL) and thermally stimulated conductivity (TSC) are closely related phenomena. Simultaneous detection of luminescence and conductivity allows one to acquire more information concerning the basic trapping processes occurring during heating of a sample. In this paper a new formula for simultaneous TL/TSC measurement is derived under quasiequilibrium (QE) conditions. Numerical analysis of the obtained experimental data requires fitting of only two unknown parameters. The new method of analysis was verified for computer generated TL/TSC curves. The practical usefulness of this method is demonstrated in application to the measurements performed for the a-alumina single crystal. The analysis, in general, confirms earlier results for the peak B'. The results obtained for the peak D' are not so clear. Most likely they reveal some complex factors that are not taken into account.
