a Schematic design of the PEGylated PbS/CdS core-shell QDs. b Normalized emission spectra of four kinds of PEGylated QDs in aqueous dispersion. c Normalized absorption and emission spectra of four kinds of PEGylated QDs mixed in a certain ratio in water. The hind limb fluorescence images of the same mouse in d 1200–1300 nm, e 1300–1400 nm, f 1400–1500 nm, g 1500–1700 nm, h 1700–1880 nm, and i 1880–2080 nm. Scale bars: 10 mm. j Cross-sectional fluorescence intensity profiles along the red dashed lines of the vessel in (d–i) and the localized magnification of the background signal. k SBR analysis of the imaging results in (d–i).
