a Anatomy of the atomic structure of Au14Cd31. Purple = core Au; magenta = surface Au; blue = Cd; yellow = S; Carbon tails are omitted for clarity. (b) UV-Vis absorption (purple) and PL (red) spectra. PL photoluminescence. c TCSPC trajectory, which is detected at 850 nm. τ PL lifetime component. d fs-TA spectra of Au14Cd pumped at 550 nm, showing the ΔT/T at all time delays between 550 and 950 nm. e Selected kinetic traces at typical wavelengths.
