a Chemical structures of a library of organic acid ligands, including butyric acid (C4), hexanoic acid (C6), heptanoic acid (C7), octanoic acid (C8), 2-hexyldecanoic acid (C16), and oleic acid (C18). b The transmission electronic microscopy images and Ultraviolet-visible (UV-Vis) absorption and photoluminescence (PL) spectra along with the photoluminescence quantum yield (PLQY) and full-width-at-half-maximum (FWHM) of the MHP NCs capped by C4, C8, and C18 ligands. The experiments are repeated 3 times to measure the PLQY and FWHM values. Source data are provided as a Source Data file.
