Synthesis and Enhanced Optical Characteristics of Silicon Carbide/Copper Oxide Nanostructures Doped Transparent Polymer for Optics and Photonics Nanodevices.

The present work aims to improve the optical characteristics of silicon carbide(SiC)/copper oxide(CuO) nanostructures doped polyvinyl alcohol(PVA) to use in various photonics and optoelectronic nanodevices like sensors, transistors, photocatalysis and photovoltaic cell. Results showed that the absorption of polymer was increased about 62.2% and transmission reduced about 53.8% at UV spectra region (λ = 200 nm) when the SiC/CuO nanostructures ratio reached (6 wt.%). The energy gap of PVA was decreased from 4.5 eV to 0.98 eV when the SiC/CuO nanostructures content reached (6 wt.%) which made it can be employed in many nanosemiconductors devices with few cost, flexible, excellent physical and chemical characteristics. Also, the results indicated to the optical parameters values of PVA were rise with increase in the SiC/CuO nanostructures content. Finally, the obtained results indicated to the PVA/SiC/CuO nanostructures have good optical characteristics which make it can be suitable for photonics and electronics fields. [ABSTRACT FROM AUTHOR]
