a Absorbance spectra of PbS QDs during growth. HWHM (meV) progressively narrows during growth (PbS nuclei: black, PbS QDs grown by BBN-SH: other colors). The TEM images of the final QDs and PbS nuclei. (inset: HRTEM image; scale bar: 20 nm). b Absorbance and PL spectra of CuInS2 QDs during growth (CuInS2 nuclei: black; CuInS2 QDs grown by BBN-SH: other colors).
