Hole and electron traps in the YAlO3 single crystal scintillator

Result description

The processes of hole and electron localization in YAlO3 single crystals were investigated by electron spin resonance. It was found that holes created by UV or x-ray irradiation are trapped at regular oxygen ions forming two types of O- hole centers. Electron type trapping sites are assigned to Y antisite ions. The yttrium antisite ions in the lattice were directly identified by 89Y nuclear magnetic resonance.
