| Abstract: | The luminescence kinetics of solutions of pseudoisocyanine iodide (PIC) J aggregates is studied upon excitation by pico- and subnanosecond laser pulses into the main superintense long-wavelength
absorption band. The dependences of the transmission and luminescence energy on the pump energy are measured. It is found
that the shape of the luminescence kinetics depends on the recording and excitation spectral regions, which is obviously related
to the energy transfer between coherently coupled fragments of J aggregates. |
