Abstract
We report the comparative morphological, structural and optoelectronic properties of ternary PIN/PPY/CdS nanohybrid material synthesized by chemical oxidative polymerization technique. The successful incorporation of CdS nanoparticles into polymeric PIN and PIN/PPY matrix was confirmed by X-ray diffraction (XRD) and Fourier transform infrared spectroscopic (FT-IR) techniques. Moreover, the field emission scanning electron microscopic (FESEM) and transmission electron microscopic (TEM) techniques are performed to study the surface morphology of the as-synthesized specimens. The as-prepared ternary nanohybrid showed a reduced optical band gap (~ 1.92 eV) evaluated through Ultraviolet–Visible (UV–Vis) absorbance spectra. From the current density–voltage (J–V) characteristics, the Ohmic conductance ~ 0.126 S was found for the ternary nanohybrid PIN/PPY/CdS. In addition, the ternary nanohybrid exhibits comparatively the higher PL intensity which indicates the higher electron–hole recombination rate. All these results indicate the aptness of the as-synthesized PIN/PPY/CdS nanohybrid towards optoelectronic device application.
