- These dyes have higher laser efficiney,larger stokes shift and excellent photostability. 这些染料有激光效率高、斯托克斯位移大及优良的光稳定性。
- The Stokes shift of the compounds in solvents is longer than 87 nm, and it is also red-shifted when the polarity of solvents is increased, In DMF, the Stokes shift is over 100 nm. 都有较大的斯托克位移(>87nm),并且随着溶剂极性的增大而增大,在DMF中都达到100nm以上。
- Correlation between polymer chain structure and fluorescence intensity wasobserved. Stokes shift and fluorescence intensity of these polymers increased withthe increase of solvents? 探讨了它们的合成条件,研究了它们在不同溶剂中的荧光性质,讨论了溶剂对它们的荧光光谱Stokes位移、荧光强度的影响及溶液浓度对它们的荧光性质的影响,考察了荧光高分子的荧光强度与高分子链结构的关系。
- From the results of PLE experiment, a large Stokes shift (SS) was observed.The large Stokes shift can be attributed to the variation in indium composition or the quantum confined Stark effect (QCSE). 透过光激萤光激发实验,我们观察到很大的史托克位移,这主要是由于铟浓度变化与量子局限史塔克效应的影响。
- The results showed that the products represented positive solvatochromism and the Stokes shifts increased with increase of polarity of the solvents. 结果表明,随着溶剂极性的增大所合成的化合物均表现为正溶剂化显色,且斯托克斯位移较大。
