Multichannel Photoluminescence of Graphene Quantum Dots Across Femtosecond to Cryogenic Timescales
Small, EarlyView.This study reveals how graphene quantum dots emit light across all relevant timescales, from femtoseconds to cryogenic steady states. By integrating optical Kerr gating, time‐correlated single‐photon counting, and low‐temperature photoluminescence, distinct intrinsic, surface, and defect‐related emission channels are temporally and spectrally ...
