摘要

Photoluminescence (PL) spectroscopy was carried out on CdZnTe crystal grown by Modified Vertical Bridgman method, with temperature from 10 K to 150 K. Abnormal temperature dependent PL intensity were observed from 30 K to 50 K, which is the so-called "negative thermal quenching". Three non-radiative processes and one negative thermal quenching process were identified. The difference of XRD spectra between CdZnTe crystals with and without negative thermal quenching behaviors gives a possible explanation on its origin.
