Title:
AU-AG CORE-SHELL NANOROD PARTICLES AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2011/071167
Kind Code:
A1
Abstract:
Disclosed are: Au-Ag core-shell nanorod particles wherein a cationic surfactant such as CTAB is substituted by an other compound; and a method for producing the Au-Ag core-shell nanorod particles. Specifically disclosed are Au-Ag core-shell nanorod particles which are characterized in that each of the nanorod particles comprises a gold nanorod particle that serves as the core, a shell layer that covers the surface of the gold nanorod particle and is formed from silver, and a copolymer that adsorbs on the surface of the shell layer. The Au-Ag core-shell nanorod particles are also characterized in that the copolymer is a block copolymer or graft copolymer that is obtained by polymerizing at least a polymerizable monomer (A) that has a group represented by general formula (I). In the formula, Ra represents an alkylene group having 2-7 carbon atoms.
