Femtosecond non-degenerate pump-probe measurements of single-wall carbon nanotubes (SWCNTs) within an ordered array of nanosize silica spheres

We present preliminary lifetime data of single-wall carbon nanotubes (SWCNTs) grown within the voids of an ordered array of silica spheres. Non-degenerate pump-probe measurements with /spl lambda//sub pump/ = 400 nm and /spl lambda//sub probe/ = 800 run indicate a decay of 319 /spl plusmn/ 25 fs.
