文摘

Cysteine doping enhances carbon nanotube emission more than other amino acids do. SWNT emission dependence on cysteine concentration is tuned by UV irradiation and pH. Type of sonication treatment influences SWNT PL dependence on cysteine concentration. Polymer coverage and defectiveness of nanotubes effect on nanotube emission. Graphic abstract.
