Effect of Titanium Nitrate Nanoparticles on Optical Properties of PVA/PEG Blend for Optoelectronics Detectors

Abstract

In this work, casting method was used to fabricate the polyvinyl alcohol (PVA)/ poly ethylene glycol (PEG) nanocomposite with different content of titanium nitrate nanoparticle (TiN NPs). This nanocomposite was analyzed to use a Spectrophotometry with a spectral region of 200-800 nm. The absorption enhances when the added TiN NPs to the polymeric matrix which may be used for various applications such as optoelectronic detector. The optical energy gap for indirect transition (allowed and forbidden) decreased as TiN NPs content increases. Moreover, all optical constants have been determined.
