Abstract

With PANI as the carrier,CdSe/PANI composite films were prepared by potential controlled electrodeposition method. The morphology, crystal structure and optic properties of the films were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and luminescence spectrum. SEM images show that the grain size of CdSe in CdSe/PANI composite films is 150—200 nm,and the grain size increases with the increase of electroplating time. X-ray diffraction result showed that CdSe/PANI composite films contained two kinds of crystals and the crystal structure of CdSe/PANI composite films didn't alter with the changes of its thickness. The luminescence spectrum showed that photoluminescence properties of CdSe/PANI composite films were greater than those of the CdSe films and PANI films. Compared with CdSe film,the existence of PANI in composite films had a role of the carrier and significantly enhanced the photoluminescence properties of CdSe,and led to the photoluminescence emission peak position red-shifted obviously.
