چکیده انگلیسی
In this paper, we report the controllable preparation of silver nanoparticles with plate-like and granule-like morphologies using mixed solvent of ethanol and water. The dosage of water was found to be critical on the morphologies and sizes of the final silver nanoparticles. Optical measurements reveal that the plate-like silver nanoparticles possess relatively high transmittance, while the granule-like ones show low transmittance and high absorption. In addition, after binding with rhodanine, the silver nanoparticles exhibit selective enhancement for different bands as SERS substrate. The Raman bands at ca. 660Â cmâ1 is higher for plate-like nanoparticles, while the Raman bands at ca. 1184Â cmâ1 is stronger for granule-like nanoparticles.
