The crystal output was compared to CaF 2 :Eu data under similar experimental conditions. For the experiments, a CPI series CMP 200 DR medical X-ray tube (exposure of 89.83 mR) was used to excite the crystal and record the produced light in a temperature range from 20°C to 140°C. The luminescence efficiency of ZnSe:Te decreases constantly with increasing temperature (8.8 efficiency units – EU at room temperature 20°C, up to 1.56 EU at 140°C), following a similar pattern to previously examined crystals (CaF 2 :Eu), however from a different starting point, due to the inherent properties and possibly to the production characteristics of the particular material sample. Data on the thermal behavior of scintillators, such as the materials in question, are useful for a variety of applications, from medical imaging to detectors for extreme environmental conditions. © 2022 The Authors.
