Summary

Undoped and Mn-doped ZnO films and ZnO nanoparticles dispersed polyvinylpyrrolidone (PVP) films were prepared on Pyrex glass substrate by the sol-gel dip-coating technique utilizing zinc acetate precursor. The thin film is extensively characterized for its surface morphology, chemistry, thickness, and nanocrystallite size using various advanced analytical techniques such as Fourier transform infrared spectroscopy (FTIR), X-ray photoetectron spectroscopy (XPS), and atomic force microscopy (AFM). Under the given processing conditions, ZnO semiconductor thin film with nanocrystallite size 15-20nm is obtained and the ZnO nanoparticles of varying shapes are uniformly distributed in the PVP polymer matrix.
