Enhanced morphological, optical and electronic characteristics of WC NPs doped PVP/PEO for flexible and lightweight optoelectronics applications

摘要

In present work, nanocomposites films of polyvinyl pyrrolidone (PVP)/polyethylene oxide (PEO) transparent matrix doped by tungsten carbide nanoparticles (WC NPs) were prepared to use in many optoelectronics and photonics devices with low cost, light weight, excellent corrosion resistance and good optical and electronic properties compare with others materials. The PVP/PEO/WC nanostructures were fabricated with various ratios of polymer matrix and tungsten carbide. Structure, electronic, optical and electrical characterizations of samples were studied. The results indicated to the nanocomposites have higher absorbance at UV spectrum. The absorption of (PVP-PEO) matrix enhanced 31.6% with adding of WC NPs. The energy band gap decreases from 3.6 to 3.22 eV. The optical parameters and conductivity of (PVP-PEO) matrix were improved with the rise in WC NPs content. The obtained results indicated that the (PVP-PEO-WC) nanocomposites are promising for different optoelectronics applications which may be used in various fields of electronics and photonics devices.
