Abstract

The thermoluminescence (TL) of three different high-temperature superconducting materials, namely ErBaCuO, YbBaCuO, and (Bi,Pb)SrCaCuO, has been measured after x irradiation at 20 K. This comparative low-temperature TL investigation has revealed a close similarity in the structure of the glow curves for all three compounds in the 20-300 K temperature range. Strongest glow peaks are shown to appear below the superconducting transition temperature. The origin of the various glow peaks is discussed in terms of radiative recombination of thermally released holes with trapped electron centers. The model is supported by further TL measurements of the ErBaCuO compound, thermally treated, in reducing and oxidizing atmospheres. It is demonstrated that the TL intensity is closely related to the oxygen stoichiometry of the material, namely, the oxygen vacancies.
