| Abstract: | Gold nanorods were synthesized in the aqueous solution via a seed-assisted approach with capping agents.Through surface modifications on Au(111) by a self-assembled monolayer,the nanorods were dispersed onto the surface via a dipping technique,making use of the electrostatic attraction of oppositely charged functional groups,and the dispersion density can be controlled by the times of dipping.An argon ion sputtering technique was proposed to clean up the organic contaminants and coating agents on the surfac... |
