The self-assembly of gold nanoparticles with C-60 nanospheres: fabrication and optical liming effect
A new amphiphilic-like C-60 derivative (DTMF) with hydrophobic-hydrophilic-hydrophobic structure was synthesized and characterized. DTMF can form nanospheres with an average size of 50-100 nm in water. Gold nanoparticles with similar to10 nm diameters are self-assembled onto the surface of DTMF nanospheres via the in situ reduction of HAuCl4 in the aqueous solution of DTMF nanospheres. The optical limiting performance of the aqueous solution of DTMF nanospheres is improved by the formation of the DTMF-Au nano-assemblies. (C) 2003 Elsevier B.V. All rights reserved.
