利用电化学脉冲沉积法在聚苯胺 ( PANI)膜上制备了纳米 Cd S/PANI复合膜 ,并利用扫描电镜光谱、紫外可见光谱、红外光谱、拉曼和荧光等光谱技术表征复合膜的形貌、结构及性质 .Cd S/PANI复合膜中Cd S微粒呈现量子尺寸效应 ;Cd S和 PANI间存在相互作用 ;由于聚苯胺和 Cd S能级的合适匹配 ,聚苯胺对Cd S的光致发光 ( PL)有增强效应 ,增强机理为光生载流子的传递机理
Nanosized CdS / PANI composite films were prepared on polyaniline (PANI) films by electrochemical pulse deposition method. The morphology of the composite films was characterized by scanning electron microscopy, UV-visible spectroscopy, infrared spectroscopy, Raman spectroscopy and fluorescence spectroscopy , Structure and properties of CdS particles in the CdS / PANI composite film show quantum size effect; there is interaction between CdS and PANI; due to the suitable matching of the polyaniline and CdS levels, the photoluminescence of CdS by polyaniline (PL) enhancement effect, the enhancement mechanism for the optical carrier transfer mechanism
