Structural and Optical Properties of Mn-Doped ZnO Thin Films Prepared by SILAR Method

Full Text PDF

Abstract:

The growth of highly textured Mn doped Zinc oxide (ZnO) thin films with a preferred (002) orientation has been reported by employing successive ionic layer growth by adsorption reaction (SILAR) using a sodium zincate bath on glass substrates has been reported. The prepared films were characterized by X-ray diffraction (XRD), optical spectroscopy and scanning electron microscopy (SEM) measurement. The XRD analysis reveals that the films were polycrystalline. Morphology of the films was found to be uniform with smaller grains and exhibits a structure with porous. The calculated Band gap value was found to be 3.21 eV prepared at 15 mM MnSO₄ concentration.
