THE MECHANISMS OF RECOMBINATION PROCESSES IN POTASSIUM МЕТАPHOSPHATE

Abstract

The research of recombination luminescence in pure and doped by Tl+, Mn2+ or NO3- ions in KPO3 is carried out. It is shown, that in a crystal and glass the recombination processes are activated at different temperatures. It is established, that the TL at 100К in crystal of potassium metaphosphate is caused by hole the mechanism of recombination. In glasslike KPO3 the TL peak at 260К is connected to the electronic mechanism of recombination.
