Metal oxides possess a broad range of electronic, chemical, and physical properties that are often highly sensitive to changes in their chemical environment. Many scientists and engineers have studied metal oxide thin films as electronic materials due to their semiconducting behavior, structural simplicity and low cost. Many researchers in the world synthesize the Metal Oxides by different methods like Chemical Vapour deposition, Electrochemical Deposition, Puled Lased Deposition, Spry Pyrolysis, Sputtering, Chemical Bath Deposition Technique, etc. The material exhibits different properties depending upon the method utilized for the synthesis. Variety of morphologies, complex structure has been developed by physical or chemical methods. However the work on controlled growth of these films is still in developing state. Therefore in present work we deposited ZnO metal oxide thin films on different substrates by Chemical Bath Deposition Technique and the influence of Microwave annealing on its Structural, Surface Morphology and Optical properties of as deposited films by XRD, SEM, FTIR and UV-VIS Spectrophotometer has been studied. The properties of the materials are determined by the grain size in the materials, the substrate on which the materials are grown, the Band Gap of the materials, the crystal structure of the materials, thickness of the films, stoichiometry of the materials, growth parameters, etc. The band gap indicates the film is transmitting within the visible range and the band gaps changes because of the grain size of the films. We also observed that, the change in preparative parameters affects the deposition rate of thin films. From the observation, it is clear that the growth rate increases as the deposition temperature, deposition time, molarities of the solution increases. It is also clear that the growth rate increases as the film thickness and grain sizes increases while band gap decreases.
