) doped polyvinyl alcohol (PVA) as a promising nanocomposites materials to utilize in numerous quantum electronics and optical nanodevices. The fabricated nanostructures have great properties compared of other nanomaterials comprised few cost, excellent optical characteristics, flexible and lightweight. The structure, optical, and electronic features of PVA/SiC/CeO

nanostructures were investigated. The structure properties included optimization, FTIR and optical microscope (OM). The optical characteristics were tested at wavelength ranged (200–800) nm. The optical characteristics results indicated that the absorbance of PVA rises about 76.9% at (λ = 240 nm, UV-spectra) while rises of 87% at (λ = 540 nm, VIS-spectra) when the SiC/CeO
