Optical and electrical characterizations of self-assembled CdS nanorods—polyaniline composites
2007
The aligned CdS nanorods are obtained by dispersing CdS in the conducting polyaniline matrix. The rods are about 50 nm in diameter and 400 nm in length. The significant changes of electronic absorption spectra of CdS nanorods and conducting polyaniline indicate the strong interaction between them. CdS—Polyaniline nanocomposites exhibit a three-dimensional Mott’s hopping process in the electrical conduction. Temperature variation of frequency dependent conductivity implies the correlated barrier hopping. The barrier height increases with the content of CdS.
