Abstract :
Photoluminescence spectra of CdTe:Cl crystals were measured at 5 K before and after irradiation by the second harmonic of a YAG:Nd laser. It was found that the Huang–Rhys factor for donor–acceptor pair (DAP) recombination increases after irradiation with laser power above the CdTe melting point which is explained by a decrease of the DAP concentration due to Cd evaporation and to the presence of the thermogradient effect.
