Summary:Dibutylated single-walled carbon nanotubes (Bu-SWNTs-Bu) with varying degrees of functionalization were prepared by two-step reductive alkylation and subsequent thermal treatment. A new photoluminescence peak at around 1240 nm was observed and increased drastically after the thermal treatment. The results indicate that thermally treated Bu-SWNTs-Bu are promising NIR photoluminescent materials. Alkylation and subsequent thermal treatment of SWNTs induces a new bright PL peak in the NIR region.
