Abstract

This present work reports about bismuth titanate [Bi Ti O , BTO] thin films with Mn doped coating on a glass substrate by 4 3 12 applying spin coating method. The prepared films are characterized by X-ray diffraction (XRD), scanning electron micros- copy, photoluminescence (PL) and Ultra Violet–Visible spectroscopy (UV–Vis). XRD analysis reveals the polycrystalline nature and orthorhombic structure of BTO thin films. Surface morphology discloses the influence of Mn doped on surface texture. Optical band gap values of BTO films decrease with respect to doping concentration. PL spectra of BTO films display broad green emission peaks at 520 nm under an excitation of 380 nm. The optical parameters like refractive index (n), extinction coefficient (α), dielectric constant (ε), optical conductivity (σ), electrical susceptibility (χ) are calculated and reported for the first time by using UV–Vis transmittance measurements. 1 Introduction of high valent cations on B-site is to eliminate the defects such as oxygen vacancy and vacancy complexes [13].
