Abstract:
The processes of photoluminescence thermal quenching in the range RT-800K 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-530K range and non-radiative mechanism of donor-Acceptor recombination began to dominate at T > 530K. © 2016 AIP Publishing LLC.
