Schematic of QD conjugation to SWNH exohedral surface. Pure SWNHs (a) were acid oxidized to produce SWNHox (b). SWNHox were functionalized with AET using carbodiimide conjugation (c) and SWNH–QD complexes (d) were synthesized using a ligand interchange approach (QDs denoted by red dots). (Color figure online)
