Abstract

Research on the optical characteristics of the ZnO thin film has been carried out with the sol-gel method and spin coating using a solution concentration of (Zn(CH3COO)2.2H2O) 0.5 M with 30 mL isopropanol as a solvent. This experiment involves the preparation process of making ZnO solution, making thin layers and testing the optical properties of thin films. use UV-Vis Spectroscopy to obtain the value of the transmittance at wavelength so as to obtain absorbance and band gap energy through the Tauc Plot. The value of transmittance obtained is directly proportional to the temperature while the absorbance is inversely proportional to the temperature because the high deposition temperature causes the reaction rate to be faster so that the absorbance value will be lower. Band gap energy obtained in the range of 3.23 eV - 3.27 eV according to the existing literature, namely the band gap at ZnO without doping produces band gap energy between 3.2 eV - 3.3 eV.
