Single-walled carbon nanotubes are a promising material for optical applications, but large band gap modulations remain challenging to realize. Here, the authors functionalize single-walled carbon nanotubes using 1,4-diiodooctafluorobutane, achieving a shift in the material’s photoluminescence to wavelengths of 1320 nm.
