A long phosphorescence lifetime is desirable for imaging and detection, however, phosphorescence is often quenched in aqueous environments limiting applications. Here, Li et al. present a strategy for the long-lived phosphorescence of carbon dots in water due to multiple hydrogen-bonding interactions
