Fractional photoluminescence quantum yields (PL QY) of a set of samples of QDs in tohiene, relative to that of quinine sulfate in 0.1 M aqueous H2SO4 after treatment with various concentrations of MeNHC, ClNHC, or HNHC, vs the values of ΔR for those samples. The excitation wavelength used to acquire the emission spectra, which are given in Figure S16 of the Supporting Information, is 4S0 nm.
