Abstract

Silica-gold composite particles were prepared by wet chemical route including impregnation method. The effect of precursor and solvent on the preparation of silica-gold particles was investigated. When spherical silica particles and PVP and hydrogentetrachloroaurate(III) hydrate aqueous solution were used as support material and precursor solution, silica-gold composite particles with light pink color successfully obtained. Obtained composite particles were characterized using FE-SEM, FE-TEM and XRD.

실리카-골드 복합체 입자를 함침법에 의하여 합성하였고, 용매와 전구체가 실리카-골드 입자 합성에 미치는 영향이 연구되었다. 구형 실리카 입자를 지지체로 하여 PVP, hydrogentetrachloroaurate(III) hydrate 수용액을 전구체로 사용했을 때, 연한 분홍색 색상을 띄는 실리카-골드 입자가 성공적으로 합성되었다. 합성된 복합체의 특성은 FE-SEM, FE-TEM과 XRD를 통하여 분석하였다.
