Near-IR transient absorption spectra of N3 dye as a probe of aggregation on nanocrystalline semiconductor films
The transient absorption spectra of N3 dye in the near-IR wavelength range were studied. To clarify the origin of the absorption peaks, the dependence of the spectra on the pH of solutions and on ligand substitution was examined, and the peak position was found to be sensitive to the aggregation state.
