Preparation method of silver nano-structure for surface enhanced Raman scattering substrate and silver nano-structure thereby

摘要

surface enhanced Raman scattering substrates present invention for the preparation of nanostructures and thus according relates to a nanostructure , the method of manufacturing a substrate for surface enhanced Raman scattering is a nanostructure according to the present invention, the conventional manufacturing method with a concentration of the silver nitrate and the reducing agent can not be inferred , the reaction temperature , stirring speed , one enemy about , a dropping rate , and the like shot by a particular enemy approximately , uniformly to be produced is the average size of the nano- structure and shape of the particles is very strong electromagnetic fields in a hot spot (hot spot) to provide a multi -polymer form as SERS signal enhancement as well as to be produced with high reproducibility , it is possible to selectively control the size of the particles , for surface enhanced Raman scattering substrate may be useful in the mass production of nano structures . ;
