Description

Silver nanorods have been synthesized with poly (vinylpyrrolidone)-assisted polyol reduction method. The observation by SEM and the measurement by EDS clearly showed that the surface of the obtained silver nanorods has been covered with the PVP layer (thickness 40~80nm). The growth of silver crystal appears to be suppressed with an increase in the thickness of covered PVP layer. Comparing with the shape of silver nanorods and the thickness of PVP layer, a possible growth mechanism of silver nanorods has been proposed.
