Optical properties of Langmuir-Blodgett films: perylene excimer formation

We report fluorescence studies of perylene excimer in multilayers of Langmuir-Blodgett (LB) films using time-correlated single-photon counting technique and fluorescence spectroscopy at 110 K. The kinetics and spectra of perylene excimer are presented. The results demonstrate perylene excimer formation in (LB) films at 110 K.
