Beta particle excited thermoluminescence of CaZrO3 phosphors synthesized by solid state reaction

In this work, the synthesis through solid state reaction and the thermoluminescence (TL) characterization of pellet shaped CaZrO3 samples is reported. X-ray diffraction confirms that orthorhombic CaZrO3 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 CaZrO3 exhibits TL properties potentially of interest for use in radiation detection and dosimetry. •The synthesis of CaZrO3 through solid state reaction in air at 1000 °C for 24 h is reported.•The thermoluminescence (TL) characterization on the potential application of solid state synthesized CaZrO3 as TL dosimeter is reported.•The synthesized phosphors exhibit thermoluminescence (TL) features that make them promising phosphors to develop TL dosimeters.
