| Popis: | This article focuses on the surface stabilization of ZnS NPs doped with Cu2+ ions by casein with relatively different concentrations through microwave method. The surface attributes of the fabricated NPs were characterized by FTIR, XRD, TEM, HRTEM, and EDS measurement which showed the incorporation of Cu ions in doped ZnS NPs. Optical properties were studied using UV–vis and PL spectroscopy. XRD pattern showed zinc blend structure for both uncapped and capped. Absorption spectrum was an evidence for the strong confinement effect in the form of blue shift. Spherical shape with 8 nm (uncapped) and 3 nm (capped) were specified from TEM images. PL spectrum covered UV and visible regions with shift in the emission peak towards a shorter wavelength side. Biological activity of capped NPs was highly effective against various bacterial strains with enhanced luminescence property, which makes them to materialize as an innovative division of antibacterial agent. |
