a FLIM experimentally collected measurements for GQDs-Sn (top) and GQDs-OH (bottom). b Time-dependent counts of GQDs-Sn and GQDs-OH at two excitation wavelengths of 405 nm and 640 nm. c Spatial superresolution allowing the separation of two spatially unresolved GQDs in space. We used the fluorescence lifetime information of different excitation wavelengths collected on the FLIMs of two GQDs to achieve spatial separation through the temporal window.
