摘要
In the hope of gaining a close look or better characterization of trimetallic nanoparticles that are expected to possess higher surface-enhanced Raman scattering (SERS) activity, we have analysed Au/Pt/Ag trimetallic nanocomposites prepared by the microwave irradiation method. The plasmon absorption of the trimetallic nanocomposites shows a linear shift with the addition of 7-azaindole. The addition of 7-azaindole on trimetallic nanocomposites and the obtained spectral, optical and electrochemical studies give a close look of trimetallic nanocomposite's structure and its properties. In addition to that, core-shell preferences and Pt adsorbed surface complex of 7-azaindole are theoretically explained.
