摘要：
A method for the size-controlled synthesis of silver nanoparticles is proposed and described. Synthesis is based on the reduction of AgNO3 in aqueous SDS solution by hydrogen. These nanoparticles are poly-disperse in size and shape and their dimensions can be easily controlled in the range of 20 to 60 nm by varying the concentration of AgNO3. Silver nanoparticles are analyzed using transmission electron microscope (TEM) and UV-vis spectroscopic technique. A comparison between the experimentally observed UV-vis spectra and the simulated one obtained from the modified Mie's theory, are made to understand the nature of shift of the SPR band.
