Influence of Substrate temperature on ZnO Thin Film deposition by Spray Pyrolysis Technique.
A. Jacquiline Regina Mary, S. Arumugam
Abstract :
Zinc oxide (ZnO) thin films were faicated on glass substrate by Spray Pyrolysis technique for the typical solution concentration of 0.05M of Zinc acetate along with Isopropyl alcohol and de–ionized water. The effect of temperatures on the quality of thin film have been studied for the fixed substrate temperatures (Ts) of 300o C,400o C and 500o C. The surface morphology of the prepared thin films were analyzed by Scanning Electron Microscopy (SEM). The structural determination was done by X–ray diffraction (XRD). It is observed that the faicated ZnO thin films were of polycrystalline in nature with a hexagonal Wurtzite structure. Using UV–Visible spectrophotometer the optical absorption characteristics of the samples were studied. The Energy band gap (Eg) were estimated for all the faicated thin films and were found to have a variation from 3.16eV to 3.31eV, as the substrate temperature was increased . An estimated band gap minimum of 3.16 eV was noticed for the film faicated for the specific Ts of 300o C.
