Figure 4

Spectral changes associated with oxidation of the photoreduced (a) Xl64-HDF and (b) CraCRY-HDF samples. The spectrum was recorded every 10 min after starting the oxidation. Insets represent the difference spectra in which each spectrum was subtracted by the spectrum at 0 min recorded at wavelengths from 400 to 700 nm.
