(a) Ionic doping modification method. In this process, oxidation from the iodine solution passivates the metal-rich surface of the CQD, reducing the naturally n-type doping. (b) Absorption spectra and TEM of the VLWIR CQD. (c) Spectral response of the VLWIR CQD photodetector (d) single pixel thermal imaging by CQD photoconductor.
