We report on low temperature luminescence measurements (2K) performed on differently prepared thin (2–10 μm) cadmium sulfide deposited on various substrates (glass, quartz, pyrex and CaF2). It is shown that epitaxial layers present exactly the same green emission as single CdS crystals. However, it is demonstrated that this green emission disappears if one improves the stoichiometry and orientation of the material. Furthermore, the shift of the surface emission between perpendicular and parallel oriented CdS is measured tp be 4 meV at 2K. Discussions about the influence of different substrate treatments and annealing processes on the luminescence spectra complete the information concerning the optical properties of thin CdS films.
