The sol gel process of C 60 NH 2(CH 2) 3Si(OC 2H 5) 3(C 60 3 Aminopro pyltriethoxysilane or C 60 KH550) mixing with CH 2OCHCH 2O(CH 2) 3Si(OCH 3) 3 (3 Glcidoxypropltrimethoxysilane or KH560) and (CH 3) 2Si(OC 2H 5) 2 (Diethoxy dimethymethylsilane, DTDS) were reported. The ormosils connecting with C 60 possessed good flexibility and mechanical strength. BET experiment showed that these materials have quite small pore. The compound can be polished on the machine. By using a Nd:YAG laser with 10 ns pulse duration and 532 nm wavelength, the optical limiting behavior of C 60 connecting with gel net was measured and demonstrated.
