PEDOT:PSS薄膜的拉曼主峰向高波数移动是什么原因
|
RT，经过后处理的PEDOT SS薄膜导电性变好，但是拉曼主峰并没有像文献里说的那样向低波数移动（表明由苯型向醌型的转变），反而移向高波数，这是为什么？ |

您好，最近看文献，“Fig. 4b shows the peak position variations of the two major peaks for the symmetric and asymmetric Ca–Cb stretching vibrations (Fig. S5†  . Evidently, except for the sample with the 3 wt% EGaddition, the additions of 3 to 5 wt% DMSO and of 5 to 9 wt% EG to PEDOT SS cause the symmetric and asymmetric Ca–Cbstretching modes shied to higher wavenumbers. These shis can be attributed to the changes in the electronic structure of PEDOT upon oxidation (doping) and rearrangement of the PEDOT chains from the coil-like benzoid structure to a more linear or extended quinoid structure as a result of the co-solvent addition.4,8,28 The expansion of chains is believed to cause the size increase in the PEDOT nanocrystals observed in the AFM images.” 拉曼主峰并向高波数移动（表明由苯型向醌型的转变），您是在哪篇文献看到拉曼主峰向低波数移动（表明由苯型向醌型的转变）？ |
