在不同表面压的ＬＢ膜上，应用光谱学和原子力显微镜学研究了由罗丹明标记的磷脂分子形成的多种聚集态．这些分子聚集态使光谱的峰值位移，谱带加宽．ＡＦＭ的形貌图进一步说明了膦脂单分子膜的不均一性．根据激子理论，以４５°取向角存在的罗丹明染料聚集体更符合－Ａ曲线． On LB films with different surface pressures, spectroscopic and atomic force microscopy studies of various aggregates formed by phospholipid molecules labeled with rhodamine. The aggregation of these molecules shifts the spectral peak and broadens the band. The topography of AFM further illustrates the heterogeneity of the phospholipid monolayer. According to the exciton theory, the rhodamine dye aggregate present at a 45 ° orientation is more in line with the -A curve.
