Název v původním jazyce
The X- and gamma-ray detection properties of CsPbBr3 perovskite crystals grown by the Bridgman–Stockbarger method
Popis výsledku v původním jazyce
In this paper we present the results of measurements on CsPbBr3 perovskite crystals grown by the Bridgman-Stockbarger method which have shown promise as X- and gamma-ray detection media. The crystal structure, trap concentration (3.45 x 1010 cm-3), specific resistivity (1.5 x 109 Ω cm) and other electrophysical characteristics which determine the spectrometric performance were examined. The X- and gamma-ray performance of planar, hemispherical and ring test detectors based on CsPbBr3 crystals of dimensions of 5.0 x 5.0 x 3.0 mm3 were evaluated. The energy resolution of the detector with ring electrodes measured using standard 241Am, 57Co and 137Cs and 60Co radioactive sources was: 2.3 keV (16%) at 14.0 keV; 2.7 keV (4.5%) at 59.5 keV; 12.0 keV (1.8%) at 662 keV and 18.6 keV (1.4%) at 1332 keV. The measured hole mobility-lifetime products (μτ) were as high as 3 x 10-3 cm2/V.
