Abstract
Monotonic dependence of the fluorescence band position on the exciting light energy has been shown in polycrystalline hexagonal
cadmium sulfide at 293 K. The observed phenomenon is interpreted on the basis of a qualitative model assuming the emission levels
initiation in the energy gap as a result of antibonding (Cd-S)*-orbital’s occupation in the course of electron excitation.
