Abstract

Cadmium dithiocarbamato complexes of piperidine (1) and tetrahydroquinoline (2) were synthesized and characterized by elemental analysis, FT-IR spectroscopy, NMR and TGA analyses. The X-ray single crystal structure of bis(piperidinedithiocarbamato)cadmium(II) complex (1) was determined. The synthesized compounds were used as single source precursors to deposit CdS films on glass substrates at 350, 400 and 450°C using the aerosol assisted chemical vapor deposition (AACVD) method. The surface morphology and the size of the CdS films were determined by AFM and SEM analyses; the crystalline phases by p-XRD analyses and the elemental composition by EDX measurements. The particle sizes were found to be in the range between 50–110nm and 100–220nm for complex (1) and (2), respectively. The electronic properties of the CdS films were analyzed by UV–Vis and Raman spectroscopic methods. Results revealed that the morphology, size and composition of the films are influenced by the deposition temperature.
