Transient effects have been observed in the photoluminescene (PL) of the GexSe1 - x system after keeping the fatigued sample in the dark at a low temperature. The intensity of the transient signal increases with the dark time. This effect suggests that band gap excitation inhibits the recombination of the PL centre.
