ABSTRACT
Firstly, three drops of the Au @ SiO2 sol add into 10 ml deionized water in the sink. After ultrasonic dispersion, assemble Au@SiO2 with AAO by electrophoretic deposition [5,6] at the voltage of 120 V, where there AAO template act as the anode. About 5 minutes later, terminate the process and dry it in the air under room temperature environment.
