Harnessing Ultralong‐Lived Triplet Excitons in Color‐Tunable Carbon Dots for Multilayer Security Platform

ABSTRACT Achieving multicolor ultralong room‐temperature phosphorescence (URTP) from a metal‐free single benzenic framework represents a fundamental challenge owing to inefficient intersystem crossing. Herein, we demonstrate a precursor engineering strategy that enables excited‐s...
