Trapping and recombination centers in cesium hafnium chloride single crystals: EPR and TSL study

Popis výsledku v původním jazyce

Charge trapping phenomena and recombination centers were studied in three Cs2HfCl6 single crystals of slightly different stoichiometry grown by the vertical Bridgman method. Electron paramagnetic resonance (EPR) spectra measured both before and after X-ray irradiation show creation of two distinct Vk centers. Thermally stimulated luminescence (TSL) spectra measured in the three samples were evidently composed of at least 2−3 strongly overlapped components within the 10−500 K temperature range. This suggested the existence of several recombination centers activated by the depletion of specific charge carrier traps. Along with decreased radioluminescence amplitude, the combined EPR and TSL study allowed us to assume the reduction of both the recombination and trap center concentration with the increased crystal quality.
