METHOD FOR MANUFACTURING SILVER NANOSTRUCTURES FOR SURFACE ENHANCED RAMAN SCATTERING SUBSTRATE, AND SILVER NANOSTRUCTURES THEREBY

摘要

The present invention relates to a method for manufacturing silver nanostructures for a surface enhanced raman scattering substrate, and silver nanostructures thereby. The method for manufacturing silver nanostructures for a surface enhanced raman scattering substrate specifies concentrations, mixing speed, one-time added amount, adding speed, and a total added amount etc. of silver nitrate and a reducing agent, which can not be inferred from the existing manufacturing methods. Thereby, the silver nanostructures manufactured have a uniform average size and provide a hot spot, which is an electromagnetic field having a remarkably strong shape of particles, such that the silver nanostructures can not only be manufactured to have reproducibility in a multimer shape, wherein SERS signals are enhanced, but also to be effective in mass-production of the silver nanostructures for a surface enhanced raman scattering substrate.;COPYRIGHT KIPO 2014;[Reference numerals] (AA) Relative activity; (BB) Adding speed, 쨉L/s; (CC) Examples 2-1 to 2-10; (DD) Examples 1-1 to 1-10
