Effect of reduction through the Spin Coating growing Silver thin Films Nanostructure

Abstract

Silver (Ag) thin-film nanostructures are prepared on the glass surface through a dependable method called spin coating. Silver nitrate (AgNO 3 ) has been utilized as precursors, proceeded by the thermal reduction in the H 2 atmosphere, and some of the chemical reductions such as sodium borohydride (NaBH 4 ) solution, and hydrazine hydrate solution (N 2 H 4 ). The effects of several reductants have been discussed. The structure, morphology, and absorbance spectra of the deposited silver thin films have been characterized and measured by using the following techniques X-ray diffraction (XRD), Scanning electron microscope (SEM), as well as UV-visible- NIR absorption spectroscopy, to study more about how the reduction procedure affects the formation of silver nanoparticles. As a result, thermal reduction in the H 2 atmosphere is more effective than the chemical reduction in aqueous sodium borohydride and hydrazine hydrate solution for growing consistently sized dispersed silver nanoparticles.
