Core-shell nanoparticles have received tremendous attention due to their extensive electronic, catalytic, optical and phototherapeutic application. Gold nanostructures are mainly used as a core because of their unique optical properties called surface plasmon resonance (SPR). However, gold nanostructures have an insufficient structural and optical stabilities in aqueous media. Therefore surface treatment is unavoidable to preserve an initial structural and optical properties. In this research, CTAB ((C16H33)N(CH3)3Br, cetyltrimethylammonium bromide, hexadecyltrimethylammonium bromide) -capped gold nanorods (GNRs) were simply coated with silica by an improved St?ber method. The UV/Vis spectroscopy and TEM imaging were used to characterize the morphology and the optical properties of GNRs or silica coated gold nanorods (GNR@SiO2). The formation of Si-O-Si linkages was attested by IR spectroscopy. The thermogravimetric analysis (TGA) confirms contents of GNR@SiO2.
