Abstract

Nanostructured tin dioxide (SnO2) is synthesized in the form of colloidal sol. Aniline monomer is polymerized in colloidal sol of SnO2 to prepare inorganic–organic hybrid nanocomposites. Optical band gap increases from 3.74 eV to 4.23 eV with increase of polyaniline concentration. The observed nonlinear current–voltage characteristics are satisfactorily explained using the Schottky type barriers. The temperature dependence of conductivity reveals three dimensional Mott's hopping process.
