Aqueous synthesis and characterization of HgTe CQDs. a Low resolution TEM images showing 8 nm HgTe CQDs and b, c HRTEM images of an individual HgTe CQD. d Absorbance and e PL data for HgTe CQDs with sizes varying from 3 to 10 nm. As size increases, the absorbance edge pushes to lower energy. For the 10 nm particles, the absorbance and PL cross into the MWIR regime. The sharp peak at 0.35 eV is attributed to ligand absorption
