摘要：

Fluorescence emission spectra of 1-pyrenedodecanoic acid (PDA) dispersed into barium stearate Langmuir-Blodgett (LB) films were measured at various PDA mole fractions. The emission intensity ratios of excimer to monomer (I//e/I//m) in the LB films were considerably higher due to good chromophore orientations than those in the films prepared by casting. The temperature dependency of I//e/I//m was examined, and a sudden decrease was observed at a critical temperature related to the destruction of the layer structure in LB films.
