Abstract: A layer of BaTiO3 thin films which is prepared using the sol-gel method are coated with different number of layers and has been annealed at 900�C. Every single layer has been baked for 20 min at 200°C. This studied about structural and optical properties through X-Ray Diffraction (XRD), UV-Vis spectrophotometer and FE-SEM. X-ray diffraction patterns of barium titanate samples show that the peaks of the diffractogram were successfully indexed with the cubic structure of BaTiO3. The BaTiO3 thin films have been analysed for optical application and it was suitable to apply as a bio-sensor, as an optical band gap calculated through UV Visible spectrophotometer even the surface are slightly rough compared to the other deposition technique.
