摘要：

In this work, we report the dosimetric characterization and the evaluation of the kinetics parameters of trapping states of ZnO phosphors obtained thought a chemical route. Pellet-shaped samples present thermoluminescence (TL) properties suitable for use as radiation detectors and dosimeters. The glow curve is composed of three peaks with the maxima at about 412, 530 and 600 K. The last peak is located into the temperature range considered most suitable for TL dosimetry applications. The activation energies and the frequency factors of trapping states involved in the TL emission were evaluated using the initial rise method, peak shape methods, and glow curve deconvolution (GCD). The values of the activation energies obtained using peak shape methods agree with those computed from GCD.
