Effect of microwave irradiation on photoluminescence spectra of CdTe:Cl single crystals at T = 2 K
Keywords:
photoluminescence, SHF irradiation, cadmium tellurideAbstract
The measurements of low temperature (T = 2 K) photoluminescence (PL) spectra of single crystals of CdTe: Cl, depending on the dose of microwave irradiation (at 24 GHz) were carried out. It was obtained that the effect of small doses was observed at exposure time up to t = 10 s. Corresponding increase of the photoluminescence intensity of all observed bands was detected. The irradiation of the samples in the range of 10 to 60 s leads to complex changes in PL spectra caused by the generation of both radiative and non-radiative centers. Non-radiative centers of defective origin in CdTe:Cl single crystals were formed due to microwave irradiation during 120 s, that results in a substantial decrease of the PL intensity.
