Abstract
The undoped and manganese (Mn) doped zinc sulphide (ZnS) thin film has been deposited on the glass substrate by sol gel dip coating method. The influence of different Mn concentration (Zn1−x Mnx S) (x = 0, 0.02, 0.04, 0.06, 0.08, and 0.1 wt%) on the structural, morphological, element composition , functional group and optical properties were investigated by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray, Fourier transmission infrared spectroscopy, UV–Visible spectroscopy and photoluminescence. In addition antimicrobial activity of as-deposited ZnS thin film has been evaluated by in vitro disk diffusion method against different microorganisms. Besides the photo catalytic degradation properties of methylene blue dye (MBD) and methyl orange dye (MOD) under UV light irradiation has been evaluated. From this investigation Mn doped ZnS thin film revelled excellent antimicrobial activity and photo catalytic degradation properties compare undoped ZnS thin film.
