Abstract

Silver thin-film nanoparticles are prepared on the glass surface through a dependable method called spin coating. Silver nitrate (AgNO3) was utilized as precursors, proceeded by the thermal reduction in the H2 atmosphere, and some of the chemical reductions such as sodium borohydride (NaBH4) solution, and hydrazine hydrate solution (N2H4). The effects of several reductants have been discussed. The structure, morphology, and absorbance spectra of the deposited silver thin films were characterized and measured by using the following techniques X-ray diffraction (XRD), Scanning electron microscope (SEM), as well as UV-visible- NIR absorption spectroscopy respectively, to study more about how the reduction procedure affects the formation of silver nanoparticles. As a result, thermal reduction in the H2 atmosphere is more effective than the chemical reduction in aqueous sodium borohydride and hydrazine hydrate solution for growing consistently sized dispersed silver nanoparticles.
