Fund Project: We thank professor Peng Cheng-hang in Institute of Biophysics Academia Sinica for helpful discussion on the results of fluorescence lifetime. The National Natural Science Foundation of China (NNSFC) and Academia Sinica was greatly acknowledged* for the financial support.

The influence of overcoating layers of dialkylglycerylether-β-glucosides(A), 1,2-O-dialkylglycerylethers(B) and.arachidic acid (C₂₀) on the fluorescence of the squaraine dye(SQ) and C₂₀ mixed film were investigated by fluorescence and time-resolved fluorescence measurements.An apparent increase in fluorescence intensity for three layer mixed film of SQ and C₂₀ were obtained by overcoating A in comparison with the small change fluorescence intensity for SQ dye mixed film by overcoating B or C₂₀.
