Abstract

Abstract:

This article describes the growth of zinc sulfide (ZnS) nanorod on glass/aluminum foil by employing butterfly wings as biotemplate. Upon calcinating (at 400°C), the butterfly wings soaked in ZnS nanoparticle suspension, with uniform cage-like nanostructures in nanodimensions, were found on glass/aluminum surface. The transverse and longitudinal dimensions of the nanorods were evaluated from scanning electron microscopy micrographs as 132 and 159 nm, respectively. Purity of the ZnS nanorod found on the specimen was checked by recording XRD (28.877°, 48.038°, and 57.174°) and Fourier transform infrared spectrometer spectra (663.7 and 551.68 cm^-1). Luminescence natures of the nanorods were examined using photoluminescence spectral studies. The characteristic emission peak is shown in the visible region with strong intensity, while the excitation peak is shown at 267 nm. Electrochemical impedance spectroscopic analysis of ZnS nanorod exhibits double-layer capacitance value (C _dl=6.7nF), and the Bode plot explains the stability of ZnS nanorod under the influence of electrical field.
