We report the first photoluminescence(PL)study ofthe smallest single-walled carbon nanotubes prepared in the zeolite *** of the metallic band structures of these nanotubes,strong photoluminescence signals have been observed using an Arlaser excitation at488 *** PL has a broad spectrum,ranging from 530to 1200 nm with a peak at 720 *** emission intensity
