Fig. 2. — UV-visible (A) and transient absorption spectral (B–E) traces of 4.2-nm-diameter CdSe quantum dots in toluene (A) and attached to SiO₂ (B), SnO₂ (C), TiO₂ (D), and ZnO (E). Transient spectra shown at pump-probe delay times of 0 (black), 1 (red), 10 (blue), 100 (cyan), and 1,000 ps (pink). Also, transient absorption kinetic traces (F) of 4.2-nm-diameter CdSe quantum dots attached to each MO substrate at the 1S_3/2-1S_e transition. Error bars are representative of standard deviation of eight measurements collected at four unique spots on each CdSe-Mo film.
