Fig. 3.
Absorption versus concentration of ZnC2 and FbC2 over a 1000-fold range. The spectra are normalized at the Qy band; the path length of the sample cell and FWHM of the Qy band are also listed in the inset. The concentrations are based on the absorbance of the ~5 μM solution measured at the B band (assuming64 ε = 160,000 M−1cm−1).
