Undoped ZnO and ZnO doped with various concentration of TiO2 (ZnO:TiO2) at 1, 3, 5, 7 and 9 wt% were prepared on ZnO seeded layer coated glass substrate by hydrothermal method. Based on XRD analysis, the crystallite size of ZnO:TiO2 thin film decreased when the concentration of TiO2 increase. The diffraction peak for all ZnO:TiO2 samples show the presence of dominant ZnO phase at (002) plane that refer to hexagonal wurtzite structure with c-axis orientation. For the UV-Vis analysis, ZnO:TiO2 thin film that have doped at 5 wt% of TiO2 concentration has the highest transmittance. This sample also shows the highest porosity with value of 1.3044. The the absorbance edge at UV range of ZnO:TiO2 doped at 5 wt% of TiO2 concentration has shifted towards lower wavelength which possibly the increasing of charge carrier. Therefore, it can be concluded that the properties of ZnO will change when TiO2 at different concentrations is doped into ZnO material. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
