Abstract

Aim: The main aim of this project is to relate optical properties such as absorbance and band gap analysis of Zinc Oxide- Nickel Oxide and pure Zinc Oxide which were prepared by using a novel wet chemical synthesis method. Materials and methods: The optical properties of pure Zinc Oxide and Zinc Oxide- Nickel Oxide were compared and the analysis is done using UV spectrophotometer. The mean of absorbance and transmittance can be obtained using SPSS software. The sample size of pure Zinc Oxide and Zinc Oxide- Nickel Oxide is 234 which in turn gives a total sample size of 468 which was calculated using clincalc which had a pretest power of 80% and error correction of 0.05. Results and discussion: It can be observed that transmittance of Zinc Oxide- Nickel Oxide is higher than the transmittance of pure Zinc Oxide. The mean of pure Zinc Oxide and Zinc Oxide- Nickel Oxide are 1.8257973 and .4588671 respectively. The attained significance of the optical characteristics is P < 0.001. Conclusion: The optical band gap of pure Zinc oxide is 6.97 eV and Zinc oxide-Nickel oxide is 1.5 eV From the results of optical characteristics, it can be seen that the mean of pure Zinc oxide and Zinc oxide Nickel oxide are 0.458867 and 1.8257973 respectively. The absorbance of pure Zinc Oxide is higher than that of Zinc Oxide- Nickel Oxide and the optical band gap of Zinc Oxide- Nickel Oxide is higher than the pure Zinc Oxide which is also evident in SPSS result.
