Description
Summary:In this work, the synthesis through solid state reaction and the thermoluminescence (TL) characterization of pellet shaped CaZrO samples is reported. X-ray diffraction confirms that orthorhombic CaZrO was obtained. The glow curve has two maxima located at 149 and 216 °C as well as a less intense maximum around 350 °C when a 5.0 °C/s heating rate is used after 64 Gy of beta particle exposure. A remarkably reproducibility of the TL response is observed in repeated irradiation - TL readouts cycles. The TL as a function of the dose displays linear dependence in the dose range from 0.5 to 256 Gy. The intensity of the maximum located around 216 °C remains 61% 14 days after irradiation, and then remains closely constant for longer times. The synthesized CaZrO exhibits TL properties potentially of interest for use in radiation detection and dosimetry.
