Optical Properties of PVA–Cr2O3–Sb2O3 Nanocomposites for Optoelectronics Fields

This study aims to prepare the PVA-Cr 2 O 3 -Sb 2 O 3 nanocomposites to utilize them in many optoelectronics fields.The optical properties of PVA-Cr 2 O 3 -Sb 2 O 3 nanocomposites are investigated in photon wavelengths from 200 nm to 800 nm.The experimental results illustrate that the absorbance (A) and absorption coefficient () of PVA are increased, while the transmittance (T) and energy band gap (E g ) are decreased with increasing of the Cr 2 O 3 -Sb 2 O 3 -nanoparticles' content.The obtained results display that the PVA-Cr 2 O 3 -Sb 2 O 3 nanocomposites might be appropriate to use in different optoelectronics applications.
