LONG-LIVED PHOTOEXCITED STATES IN POLYDIACETYLENES: THE PHOTOINDUCED-ABSORPTION SPECTRA OF PDA-4BCMU
We report the results of steady-state photoinduced absorption experiments on PDA-4BCMU grown on silica substrate. We observe three photoinduced absorption bands at 0.82, 0.95, and 1.39 eV whose relaxation dynamics are identical for the two low-energy peaks but different for the 1.39-eV band. On the basis of the spectra, the pump intensity,...
