Investigating the Optical Properties of PVA/PEG/CeO2 Nanocomposites for Optics Devices

The purpose of this work is to fabricate of PVA/PEG/CeO2 nanocomposites and examining their optical characteristics used in different optical devices.The PVA/PEG/CeO2 nanocomposites were prepared by using casting method with different concentrations of PVA/PEG blend and CeO2 nanoparticles.The optical properties were tested at wavelengths range from 200nm to 800nm.The analysis showed that the CeO2 NPs content was increased, the absorption of PVA/PEG/CeO2 nanocomposites was enhanced whereas the transmittance was reduced.Whenever the CeO2 NPs content was increased, the band gap was reduced.With addition of CeO2 NPs, the other optical properties of PVA/PEG/CeO2 nanocomposites were enhanced.Lastly, the optical characteristics outcomes showed that the PVA/PEG/CeO2 nanocomposites are being used in a variety of optical devices.
