Влияние высокотемпературной обработки на люминесцентные и дозиметрические свойства наноструктурного оксида магния

Abstract

Luminescent properties of nanostructured MgO were studied. Application in high-dose radiation dosimetry was observed. Annealing at 1673K was carried out and it was shown to cause 103 times increasing Termally Stimulated Luminescence (TSL) peak intensity. It has been suggested that the F centers define luminescent property change of nanostructural MgO at high-temperature annealing. Dose dependence gains sublinear character after annealing and sample becomes suitable for TSL dosimetry of electron pulse radiation.
