Abstract- In this paper TiO2 nanoparticles (TiO2 NPs) were completely embedded in biocompatible and biodegradable poly(vinyl alcohol) (PVA) polymer. The obtained results were exhibited that upon substituting TiO2 NPs in PVA polymeric matrix an electrical dipole moment could be induced onto the surface of TiO2 NPs and it can increase the band gap energy due to the induced Stark effect and subsequent degeneracy of energy levels. This effect was detected by utilizing a simple spectroscopic technique.
