Abstract
The thermally stimulated luminescence of oxides, carbonates and high T -c ceramic superconductors (perovskites of the (BiPb)SrCaCuO type obta ined by solid state reaction) was measured in the temperature interval 20-500 degrees C. The glow-curves obtained on the perovskites are com pared with those determined for both the precursor compounds and pure (BiPb)SrCaCuO powders of the same stoichiometry. The analysis of the d ata evidences the possibility of characterising the oxides and carbona tes and of detecting very low intensity TL signals produced in the sup erconductors by precursor compounds, which can be identified in some c ases, and/or low amounts of semiconducting or insulating compounds pro bably formed during the sintering procedure.
