Optical Characterization of Calcium Sulphide (CaS) Thin Films by Chemical Bath Deposition
Abstract: Thin films of Calcium sulphide were deposited on glass microslides using chemical Bath Deposition technique. The films were deposited at room temperature. The optical characterization was carried out which shows low absorbance, high transmittance in the uv-visible region. The photon energy and band gap is determined. These films because of their high transmittance in the UV-Visible region are suitable for various optical applications as photosynthetic, window coating and anti reflection coating material.
Keywords: Calcium sulphide, Thin film, UV- visible, photon energy, Bandgap
