Abstract
Acceptor annealed Zinc oxide (ZnO) based donor polyaniline (PANI) composite was synthesized via in-situ polymerization and sensitized with silver/silver chloride (Ag/AgCl) particles for enhancing the optoelectronic response. The sensitized composite is characterized, and the electron transfer mechanism is explained in detail. The absorbance wavelength enhanced for the sensitized composite is the result of a synergistic combination of annealing and sensitization. Elemental composition revealed the formation of sensitized composite inferred via energy dispersive spectroscopy (EDAX) using high-resolution transmission electron microscopy (HRTEM) and filed-emission scanning electron microscopy (FESEM). Selected area diffraction (SAED) pattern unveiled the coexistence of the amorphous and crystalline phase. The change in dipole moment and polarizability of molecules was evaluated using Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy, respectively. Current-voltage (I–V) characteristics proved annealing of ZnO and sensitization of polyaniline composite with annealed ZnO beneficial for current enhancement, which was further validated via cyclic voltammetry in the form of redox reaction current response.
