Synthesis And Characterization Of Silver Sulfide Nanoparticles Of Various Morphologies Using Chitosan As Stabilizer

Synthesis of Silver Sulfide nanoparticles of various morphologies were successfully done through colloidal synthesis technique at relatively low temperature using Chitosan bio polymer as stabilizer. The effect of change in stabilizer concentration,reagent concentrations and reaction temperature at constant pH on morphology and optical properties of synthesized products are also studied. It was found that reagent concentration and temperature both played important role in change in morphology of synthesized product. The crystal structure studies of synthesized products were carried out by powder X-ray diffraction technique which reveals the formation of Acanthite monoclinic Ag2S crystal structure and SAD was taken for only two samples whose analysis using XRD was difficult. The optical properties and quantum confinement effect of the products were confirmed by means of spectroscopic measurements. Morphologies obtained were characterized by SEM. Further the functionality and effectiveness of stabilization process were established by Fourier transform infrared spectroscopy.
