Oxygen pressure effects on optical properties of ZnO prepared by reactive puled laser deposition

The deposition processes of the ZnO films have been conducted in this paper. The Q-switched Nd:YAG laser of 10 ns duration and 900 mJ of energy was utilized to perform the deposition process of ZnO\glass heterojunction. At different oxygen pressure, the optical properties, and constant of the deposited samples have been tested. Under 300 °C heating treatment, and different oxygen pressure the results recorded an a higher transparency of more than 80% was also listed with a reduction in its value alongside with the reduction of the substrate temperature. Further, the energy bandgap has found to be 3.26 electron-volts.
