摘要：

The luminescence of thin (2 mu m) CdS films formed by laser ablation was investigated in the range 480-520 nm at 300 K. It turned out that the luminescence properties depend crucially on the substrate. As a main result, CdS films on glass exhibited an emission peak at the gap (around 505 nm) of thin CdS films in contrast to films on quartz. This observation is explained by the disturbed stoichiometry of thin CdS films on quartz. Furthermore, we have demonstrated that both Fabry-Perot interferences and position of the fundamental absorption edge of the thin CdS films do not depend on the substrate.
