Effect of the Yttrium Oxide (Y2O3) Nanoparticles on the Optical Properties of the Polyacrylamide (PAAm)

In this paper, the (PAAm/Y₂O₃) nanocomposites was prepared via casting process with different contented of Y₂O₃NPs (1, 3 and 5wt.% ). The opticalproperties was investigated. The optical characteristics, such as optical density, coefficient of absorbance, index of refraction, coefficient of extinction, dielectric constant of real and imaginary and optical conductivity, showed a growing trend with increasing Y₂O₃ NPs concentration in the experiments. However, when the concentration of Y₂O₃ NPs increased, a reduction correlation was seen between these two parameters (transmittance and indirect energy gap, both allowed and banned. Finally, from this result can be used these nanocomposites as the photodetectors application specially in the UV region.
