Abstract
It has succeeded in growing TiO2 18NR-T thin film using T-49 screen printing method with an annealing treatment temperature variation of 200°C, 450°C, 500°C and 550°C for 1 hour. The result of TiO2 18NR-T thin film will be characterized using UV-visible Spectrophotometry (UV-Vis). Characterization with UV-Vis obtained a result that treatment with 4 variations of temperature influence absorbance value and transmittance. The greatest absorbance value was obtained in the sample with temperature treatment 550°C while the largest transmittance value was obtained at temperature 200°C. The absorbance peak is at the wavelength of ultraviolet light. Optical band values in each temperature variation are obtained at 3.53 eV; 3.46 eV; 3.38 eV and 3.2 eV.
