PHOTOINDUCED PHASE SEPARATION OF GOLD IN TWO-COMPONENT NANOPARTICLES TO FORM NANOPRISMS

摘要

Abstract PHOTOINDUCED PHASE SEPARATION OF GOLD IN TWO-COMPONENT NANOPARTICLES TO FORM NANOPRISMS Nanoprisms containing silver and gold are disclosed. The nanoprisms exhibit the properties of pure silver nanoprisms, but are less susceptible to silver modification or reaction by a surrounding environment than pure silver nanoprisms due to the presence of the gold. The gold surface of the nanoprisms can be further modifier, using known gold-modification techniques.
