Influence of Different Annealing Temperatures on the Structural and Optical Properties of TiO<sub>2</sub> Nanoparticles Synthesized via Sol-Gel Method: Potential Application as UV Sensor

In this research, TiO2 thin films were prepared using a simple sol-gel spin coating process. The films were characterized using Field Emission Scanning Electron Microscopy (FE-SEM), Energy Dispersive Ray (EDX), X-ray diffraction (XRD) and Ultraviolet–visible Spectrophotometer in order to investigate...
