X-RAY-IRRADIATED KTiOPO4: ESR STUDIES

The study of radiation paramagnetic centres (RPC) arising in flux-grown KTiOPO4 (KTP) single crystals at X-ray-irradiation at 300 K was conducted by the ESR-method in the temperature range of 3.7÷300 K. For the first time in X-ray-irradiated KTP there were found electron and hole RPC stable at room temperature and related to Ti3+ and Al3+ impurity, respectively.
