摘要：

The interrelation between particle size, crystal structure and optical properties in semiconductor nanocrystalline thin films has wide spread interest. We report here an attempt to relating the size and structure of cadmium sulphide (CdS) nanocrystalline thin film with variation of pH of the solution. CdS particle sizes between (3.5 to 5.3nm) were obtained by varying the pH between 1.6 to 2.2 and using polyvinyl alcohol as a capping agent in a chemical route. X-ray diffraction (XRD), UV-Visible spectroscopy, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) were used to characterize the samples.
