The emission, absorption, stimulation and quenching spectra of ZnS and CdS single crystals are investigated. The importance of making all these experiments on the same sample is pointed out. The energetic levels scheme is derived for self-activated or Cu-activated ZnS and CdS.

3350 - Fluorescence and phosphorescence; radiationless transitions, quenching (intersystem crossing, internal conversion).
