Fig. 3: TA and kinetic characterization of CDs.
From: Electron–phonon coupling-assisted universal red luminescence of o-phenylenediamine-based carbon dots

TA spectra of a DA-CDs, b IL-CDs, c DCD-CDs, and d P-CDs. Kinetic traces at different probe wavelengths (e–h). TA spectra of the four CDs at the indicated delay time from 0.5 ps to 2.7 ns (i–l)
