Abstract
In this research we investigated the effect of anneal temperature change on the structure and optical properties of thin zinc oxide film by rotating sol-gel coating on glass substrate. 300°C, 400°C, 500°C and 600°C respectively. Crystal structure analysis with X-ray diffractometer Scherrer equation was used to determine the size of the crystals. The size of the crystals was 30-48 nm. The surface of the film was scanned by scanning electron microscope. Analysis of optical properties with UV spectrometer. It was found that the effect of anneal temperature variation on the light transmission and absorption of the film was 80-90%. The wavelength ranges from 300 to 375 nm. Finally, the gap between the energy bands is between 3.20 and 3.24 electron volts(eV).
