Popis: Bis(dibutyldithiocarbamato)metal complexes of cadmium and zinc were synthesized as precursors for growth of thin films of cadmium sulfide (CdS) and zinc sulfide (ZnS) by aerosol-assisted chemical vapor deposition on glass substrates. The decomposition of the precursor complexes was observed by thermogravimetric analysis, and it took place at 350–450°C with toluene used as the solvent. The CdS and ZnS films were analyzed by X-ray powder diffraction, scanning electron microscopy and energy-dispersive X-ray analysis. The preferred orientation of the crystallites within the films changed with respect to the deposition temperature. The scanning electron microscopy and energy-dispersive X-ray analysis results showed the uniform distribution of CdS and ZnS in the films, which makes them useful photoconducting materials on a structured surface.
