The Preparation and Stability Study of Silver Triangle Nanoparticle
Silver triangular nanoparticles were prepared by irradiating silver seed colloid with controlled PH at room temperature. The surface enhanced Raman activity and the time stability of asprepared silver triangular nanoparticles were investigated by experiments. The comparative analysis results of transmission electron microscopy images, UVvisible spectroscopy and Surface Enhanced Raman Scattering (SERS) spectroscopy of asprepared sample and sample deposited for 5 months in dark room at room temperature show that the geometric shape, size and maximum absorption wavelength of deposited sample are essentially unchanged, which indicate that asprepared silver triangular nanoparticles have better time stability. And the deposited sample exhibits strong SERS activity for rhodamine 6G molecules.
