    • The QD PL quantum efficiencies were determined by comparing the integrated emission of a given QD sample in dilute hexane solution with an optical density of 0.1 with that of the laser dye Coumarin 102 (Lambda Physik) in ethanol.

    • note
    • WDS confirmed the thickness of the ZnS shell for the QD sample shown in Figures 2b and 5c, giving an average element weight percent of 21.6 ± 0.9% for Cd, 32.2 ± 0.5% for Zn, and 46.2 ± 0.7% for S. These values correspond to a 0.77 nm (2.5 monolayers) thick theoretical ZnS shell, which is consistent with the average experimental thickness obtained from TEM.
