Multi‐Dimensional Color Tunable Long Persistent Luminescence in Metal Halide‐Based CPs Through Precise Manipulation of Electronic and Steric Effects

in ligands. Moreover, owing to the co-existence of single molecule and aggregated triplet excitons, these CPs also realize dynamic color-tunable LPL from green/orange to yellow/red depending on the excitation wavelength, temperature, and time-evolution. Based on quite different LPL of these CPs, multiple anti-counterfeiting methods are proposed.
