Influence of aluminum nanoparticle integration on the structural and optical properties of PVA composite films
Composite films consisting of polyvinyl alcohol (PVA) are integrated with a varying amounts of aluminum nanoparticles (Al NPs) (0.0, 0.04, 0.08, 0.1wt%). The samples are produced using the casting technique. The composite films are synthesized to achieve a good optical and electrical properties for optoelectronic photonic device applications such as solar cells and energy storage applications. Structural analysis is done using X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The XRD analysis reveals the complete dissolving of Al Nps in the PVA matrix and a reduction in its crystallinity (Xc) from 43 to 22% with the increase of Al NPs concentration. The FTIR spectra indicated significant changes within the 1100–500 cm−1 range upon the correlation of Al NPs with PVA due to the formation of cross-link between Al NPs and oxygen atom in PVA. Additionally, high-resolution transmission electron microscopy (HRTEM) is done to determine the distribution and the average size of nanoparticles in polymeric films, the HRTEM reveals the indexed planes of Aluminum (Al) crystalline lattice. Ultraviolet–visible (UV–Vis) spectroscopy is done to investigate the optical properties of the samples. The results show that the electronic transition in the samples is indirect transition. The indirect optical energy gap is slightly changed as the Al NPs concentration increased, while the refractive index increases from 2.2 to 5.9 as the Al NPs concentration increased.
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
