Abstract

AbstractPhotoluminescence measurements aimed at defining the precise nature of scintillation reported in paratellurite (TeO2) crystals [Coron et al., Nucl. Instrum. Methods Phys. Res. A 520, 159 (2004)] are presented. Measurement results are discussed for TeO2 crystal samples (pure and Mg, Mn, Nb, Zr doped) studied for their photoluminescence properties in the 30–300 K temperature range and the nature of scintillation peaks reported on these samples is explained. Conclusions are drawn concerning the possibility to improve the scintillation yield of TeO2 crystals to be used as cryogenic bolometers operated at 10 mK in experiments studying the ββ decays of 130Te.
