Abstract
The blue and green components of the glow of ZnS: Cu: Cl crystals were recorded separately. Thermoluminescence-excitation spectra taken for each of the components were found to be identical with the excitation spectra for the blue and green luminescence at steady excitation. Other measurements included the spectral distribution of the glow, saturation effects, effects of infrared radiation, and computation of activation energies. The activation energy for the blue peak was found to be about 0.14 ev, and that for the green—about 0.20 ev. From the shape of the peaks it was concluded that the recombination process is bimolecular in character.
