Thick films of pure SnO2 and composite 1%, 3%, 5%, 7% and 9 % ZnO incorporated into pure SnO2 were prepared by
standard screen printing technique. All samples were dried and fired at 5000C at 5 hours. Thick films of SnO2 and composite
1%,3%,5%,7% and 9 % ZnO incorporated into pure SnO2 were characterized by SEM, EDAX, XRD, FTIR and UV to study
surface morphology, elemental analysis, crystalline Phases of films, vibrational and spectroscopic study respectively. The UVvisible spectroscopic study was undertaken in terms of absorbance and absorption coefficient with percentage composition.
