The photo luminescent spectra have been studied at room temperature for the Lipid A Langmuir-Blodgett monolayers grown on various substrates of Au, Si and SiO@sub 2@. The maxima of the spectral profiles are shifted towards long waves as compared to the spectra of 10@super -2@% DMSO solution and water suspension of the lipid. The energy difference of approximately 0.4 eV is, likely, attributed to the molecule-molecule and molecule-surface interaction of the monolayer. The luminescence has been stimulated with pulses of UV laser (337 nm, 100 Hz, 8 ns) or UV lines of Xe lamp and registered with photon counter with the coincidence circuit. The lipid A were extracted from the membrane of Ralstonia Solancearum.
