Temporally fluctuating SERS signals from molecularly-bridged Ag nanoparticle dimers

Abstract

Preparation, TEM imaging and measurements of temporally fluctuating (blinking) SERS signal of Ag nanoparticle dimers and small aggregates (from dimers to hexamers) bridged by diaminoazobenzene molecules are reported
