The two-stage, green-edge fluorescence at 4.2°K of single crystals of CdS excited by laser-produced red light was examined. The green-edge emission was found to be very similar to that produced by ultraviolet excitation. However, a green-edge shift to longer wavelengths, as well as no evidence of a blue-edge emission, was found. These effects could be explained by the existence of a distant-pair recombination process for the green-edge emission, and a low rate of free electron—hole production.
