荧光物质对光的吸收和重新发射之间能量损失所引起的谱带分离,即Stokes位移,是众所周知的现象。根据溶剂-荧光分子之间相互作用来阐明溶剂的性质、结构和温度等因素对Stokes位移的影响已有大量报道。有关聚合物介质的影响也已有研究。Sah和Eisenbach等通过改变介质温度及聚合物中添加稀释剂以改变高分子的分子运动难易程度,并 It is a well-known phenomenon that the band separation caused by the energy loss between the absorption and the re-emission of light by the fluorescent substance, that is, the Stokes shift. According to the interaction between solvent and fluorescent molecules, the influence of solvent properties, structure and temperature on the Stokes shift has been reported. The impact of polymer media has also been studied. Sah and Eisenbach and so on by changing the temperature of the medium and the polymer to add diluent to change the molecular motion of the polymer difficult, and
