Thin amorphous nanostructured CdS films were photochemically obtained via direct UV radiation (lambda = 254 nm) of complex Cd[(CH3)(2)CHCH2CH2OCS2](2) on Si(100) and ITO-covered glass substrate by spin coating. Thin cadmium xanthate complex films' UV photolysis results in loss of all ligands from the coordination sphere. X-ray photoelectron spectra for as-deposited US thin films show the most representative signals of Cd 3d(5/2) located at 405eV, Cd 3d(3/2) located at 412eV and a small signal S 2p located at 162 eV. The surface morphology of the films was examined via atomic force microscopy. This can be described as a fibrous-type surface without structural order, which is characteristic of an amorphous deposit. The optical band gap value was 2.85 and 3.15 +/- 0.1 eV.
