The pure and Ca doped TiO2 thin films with 1 – 10% mol of Ca concentrations were prepared by sol-gel method and deposited on glass substrates with dip-coating. All samples were annealed at 500 °C for 1 h and characterized by field emission scanning electron microscope (FESEM), UV-Vis spectrometer, and fluorescence spectrometer. From the experimental results, all thin film samples exhibited the anatase phase of crystalline structure. The surface morphology and crystal size were sensitive to Ca doping concentration. All of film samples displayed clearly higher 80% of transmission in the visible range. In additional, the fluorescence intensity of the thin films samples decreased with increasing the Ca doping concentrations.
