Novel microcrystalline ZnO-CdSO4 thermoluminescent phosphors were synthesized by thermal annealing of chemically-modified ZnS powders, obtained by precipitation. Pellets exposed to beta radiation showed that the thermoluminescence response increases linearly as the radiation doses increased in the 25-300 Gy range. The glow curve exhibited two maxima centered at 112 and 216 degrees C. The latter displays a remarkable stability when the phosphor is stored at room temperature. The results indicate that these new ZnO-CdSO4 phosphors are promising detectors and dosimeters for beta radiation. (c) 2006 Elsevier B.V. All rights reserved.
