Abstract :
Solid single-walled carbon nanotube (SWCNT)/silica composites were prepared by a sol-gel method. Their third-order susceptibilities were estimated by using z-scan technique at 532 nm and 1064 nm, respectively. The results reveal negative nonlinear refraction and saturable absorption, which magnitudes depend on kinds of used SWCNTs prepared by different techniques.
