| Abstract: | In this paper the polydiacetylene (PDA) Langmuir-Blodgett (LB) films, which have potential applications in industry, are studied by using photoacoustic spectrum (PAS) combined with optical absorption and fluorescence spectra. The synthetical analysis of PAS and optical absorption and fluorescence spectra for PDA LB films that underwent environment with different kinds of gases shows that the information about relaxation process of excitation state and feature of elementary excitation can be achieved. Besides, fluorescence quantum efficiency was discussed. The achievment of this paper shows that the PAS technique is a valid means for studying LB films and can capture information which cannot be achieved by other optical spectroscopy. |
