Noncovalent Attachment of PbS Quantum Dots to Single- and Multiwalled Carbon Nanotubes
Figure 4
Attachment of commercially obtained oleic acid stabilized PbS-QD to 1,2-BDMT functionalized SWNT by ligand exchange. (a) depicts results obtained by using quantities of PbS-QD suspension enumerated in the experimental section while (b) shows results of using 50 times more PbS-QD suspension than that enumerated in the experimental section. Scale bar in both (a) and (b) is 50 nm.
