Abstract
Thin films of PdCdS ternary compound have been successfully deposited using chemical baths containing cadmiumacetate, lead acetate thiourea and ammonia. The films were characterised using a variety of techniques. X-ray diffractionanalysis revealed that a number of prominent high intensity diffraction peaks originating from reflections of the tetragonallead sulphide structure. Several smaller low intensity peaks related to reflections of the hexagonal structure of cadmiumsulphide, were also observed. Scanning electron microscopy showed a compact layer with a surface composed of platelikeshaped nanocrystals of different dimensions with well defined boundaries. Energy dispersive X-ray spectroscopyconfirmed the presence of lead cadmium and sulphide. The band gap determined from optical absorption spectroscopywas found to be 1.9 eV.
