Abstract

Nanocomposites materials of fe2o3 with poly ethylene oxide and poly vinyl pyrrolidone were synthesized by chemical method using ammonia as a reduction agent. Fe2o3 based nanocomposites deposited as film by drop casting technique on glass substrates. The effect of polymer matrix type on the optical properties (absorption and direct and indirect band gap) were investigated. It was observed from the absorption spectra of the various synthesized materials that the type of polymer used in the preparation process has a very important influence on the location of the absorption peak as well as the amount of the energy gap.
