Abstract
The processes of photoluminescence thermal quenching in the range RT – 800 K of h-BN micropowder in the 3.56 eV band were studied. It was found that two non-radiative channels of excitations relaxation with activation energies of 0.27 and 0.81 eV control the quenching for emission observed. It was assumed that emptying the shallow traps based on ON-centers characterized external quenching in RT – 530 K range and non-radiative mechanism of donor-acceptor recombination began to dominate at T > 530 K.
