Description
Summary:Surface Plasmon Resonance (SPR) of silver nanostructures varies with its shape and size. In the present work silver nanoparticles, nanowires and nanocubes were synthesized by solvothermal method by reducing AgNO3 with ethylene glycol using PVP as the absorption agent and adding different amounts of NaCl to the solution. The size and shape of the nanostructures can be controlled by varying the concentration of NaCl and solvothermal growth duration. These nanostructures exhibiting different SPR properties are evaluated as SERS substrates using R6G molecules. The Raman signals are found to be enhanced in the presence of nanostructure SERS substrate.
