The processes of hole localization in Y3Al5O12 and Lu3Al5O12 single crystals are investigated by electron paramagnetic resonance (EPR) and thermally stimulated luminescence (TSL). It is found that holes created by x-ray irradiation at 77 K are predominantly self-trapped at regular oxygen ions forming an O− hole center.
