A study of the characterization of CdS/PMMA nanocomposite thin film

Abstract

Nanocomposites of polymer material based on CdS as filler material and poly methyl methacrylate (PMMA) as host matrixhave beenfabricated bychemical spray pyrolysis methodon glass substrate.CdS particles synthesized by co-precipitation route usingcadimium chloride and thioacetamide as starting materials and ammonium hydroxide as precipitating agent.The structure is examined by X-ray diffraction (XRD), the resultant film has amorphous structure. The optical energy gap is found to be (4.5, 4.06) eV before and after CdS addition, respectively. Electrical activation energy forCdS/PMMA has two regions with values of 0.079 and 0.433 eV.
