| 摘 要： | 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．

| Abstract: | Molecular aggregates of rhodamine labeled phospholipid T1391 on LB films at different surface pressures have been investigated by optical spectroscopy and atomic force microscopy (AFM). Differenttypes of molecular aggregates which show peak shifting and band broadening in the spectra were confirmedby the morphological AFM image. The rhodamine chromophores in the aggregates were suggested to orientat an angle of about 45 degree on the mica surface based on exciton theory and suuface pleasure-areaisotherm. |
