The luminescence spectral characteristics of eosin, erythrosine, and rose Bengal molecules in reverse micelles of sodium bis(2-ethylhexyl)sulfosuccinate were investigated. Inclusion of the dye molecules in the reverse micelles leads to an increase of their hydrodynamic radii R_h, and a linear relationship is observed between this increase ΔR_h and the degree of hydration w. The increase of R_h leads to shift in the absorption and fluorescence spectra and increases the Stokes shift. The ratio of the dipole moments of the molecules in the excited and ground states μ_e/μ_g increases with increase of R_h.

各种尺寸反向胶束中荧光素家族标记的发光光谱特征

研究了双（2-乙基己基）磺基琥珀酸钠的反胶束中曙红，赤藓红和玫瑰红分子的发光光谱特征。将染料分子包含在反胶束中会导致其流体动力学半径R _h增大，并且观察到该增大的ΔR _h与水合度w之间存在线性关系。R _h的增加导致吸收光谱和荧光光谱的偏移，并增加了斯托克斯偏移。分子的偶极矩的激发态和基态μ的比_ë /μ_克用的增加而增加- [R _ħ。
