| Measurements of steady state and transient stimulation and quenching of photocurrent and luminescence were performed in ZnSe single crystals doped with Cu which exhibit marked change in the photoconductivity and luminescence when illuminated by infrared light simultaneously with shorter wavelength radiation. A model which might explain all IR induced phenomena on the basis of donor-acceptor pair recombination mechanism including releasing holes from deep center by IR light and energy redistribution between different recombination centers is presented. |
