Synthesis and Boosting the Morphological, Structural and Optical Features of PEO/Si₃N₄/CeO₂ Promising Nanocomposites Films for Futuristic Nanoelectronics Applications

The hybrid nanomaterials doped organic polymer can be considered as a promising nanosystems to apply in various optical and electronics fields. In present work, the nanocomposites films based on polyethylene oxide(PEO) filled by silicon nitride(Si₃N₄) and cerium oxide(CeO₂) nanostrucures were synthesized to employ in numerous advanced electronics and optical approaches. The PEO/Si₃N₄/CeO₂ nanocomposites have unusual characteristics compared of other nanocomposites included exceptional optical characteristics, inexpensive, superior chemical and physical properties. The optical and structural characteristics of PEO/Si₃N₄/CeO₂ nanocomposites are investigated. Results indicated the absorbance of PEO was rise of 53% in the wavelength(λ)=320 nm (UV-spectrum) while its increased of 23% in the λ=520 nm (VIS-spectrum) and 22.3% in the λ=720 nm (NIR-spectrum) when the Si₃N₄/CeO₂ NPs content reached of 7.6 wt.%. The transmittance decreased of 64% at λ=320 nm and its reduced of 19.9% at λ=720 nm, these results make the PEO/Si₃N₄/CeO₂ nanocomposites are important and promising nanomaterials for optical and electronics fields. The energy gap was decreased from 4.2 eV to 2.3 eV with increasing Si₃N₄/CeO₂ NPs content to 7.6 wt.%. The other optical factors of PEO enhanced among boosting Si₃N₄/CeO₂ NPs content. Finally, the attained results demonstrated the PEO/Si₃N₄/CeO₂ nanocomposites are promising nanostructures and important key for development of optical and nanoelectronics applications.
