The dispersion of CdTe tetrapods in a conducting polymer and the resulting charge transfer is studied using a combination of confocal fluorescence microscopy and atomic force microscopy (AFM). The results of this work show that both the tetrapod dispersion and charge transfer between the CdTe and conducting polymer (P3HT) are greatly enhanced by exchanging the ligands on the surface of the CdTe and by choosing proper solvent mixtures. The ability to experimentally probe the relationship between particle dispersion and charge transfer through the combination of AFM and fluorescence microscopy provides another avenue to assess the performance of polymer/semiconductor nanoparticle composites.
使用共聚焦荧光显微镜和原子力显微镜（AFM）的组合研究了 CdTe 四角锥在导电聚合物中的分散以及由此产生的电荷转移。这项工作的结果表明，通过交换 CdTe 表面的配体并选择适当的溶剂混合物，不仅可以大大提高 CdTe 四角锥的分散性，还可以增强 CdTe 和导电聚合物（P3HT）之间的电荷转移。通过 AFM 和荧光显微镜的组合来实验性地探测颗粒分散和电荷转移之间的关系的能力为评估聚合物/半导体纳米粒子复合材料的性能提供了另一种途径。
