Synthesis and Characterization of Ag - Soda Glass Nanocomposites


Article Preview

In the present work we have used Physical vapour deposition (PVD) technique followed by thermal annealing to synthesize Ag-soda glass nanocomposite samples. This technique offers a great deal of promise in terms of general simplicity of operation, minimal requirements for sample preparation, ease of adaptation to automated operation, and potential for scale up to production levels of material throughput. Ag-glass nanocomposites were synthesized by deposited Ag on glass slides and the resulting samples were annealed in air at various temperatures from 400 °C to 550 °C for 1 hour. Optical absorption spectrum of the resulting nanocomposites was measured in the range from 190 nm to 900 nm using UV-Visible absorption spectroscopy. The appearance of SPR peak characteristic of Ag nanoparticle formation around 420 nm in optical spectra of annealed samples indicates towards the formation of silver nanoparticles in soda glass. The size of silver nanoparticles has been found to increase with increase in annealing temperatures. Structural properties of resulting nanocomposites were also studied using TEM and FE-SEM alongwith EDAX spectra. Synthesized composites are more conducting than pristine glass and conductivity increases with increase in size of Ag nanoparticles embedded in glass. Possible mechanism for increase in conductivity has been discussed.
