“…This is caused by defects being produced, new states being created in the forbidden region, and the distance between the valence and conduction bands being lessened. 44 Similar behavior of decreasing the bandgap was observed for PVA/graphene/Fe 2 O 3 45 and PVA/PVP/SnS 46 systems. Such results are beneficial for optoelectronic device construction.…”

“…This behavior is in accordance with previous studies. 24,48,49 This decline can be credited to the formation of chemical bonds between the polymeric matrix and nanofiller, leading to the generation of localized states within the energy bands spanning the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO). This observed reduction in the E g values of PVA/SA-CsBr NPs renders them promising materials for applications in optoelectronic devices and electrochemical systems, such as polymer electrolytes.…”

This study investigates the use of organic and inorganic nanostructures to create innovative functional materials with applications in optoelectronics devices. Specifically, nanocomposite films were created by incorporating different concentrations of cesium bromide nanoparticles (5, 10, and 15 wt%) into a polyvinyl alcohol (PVA) and sodium alginate (SA) polymer blend (50/50 wt%) through a solution casting process. The impact of CsBr NPs on the structural, optical, and electrical properties of the virgin PVA/SA matrix was systematically investigated. x‐ray crystallography investigation verified the semicrystalline nature of the PVA/SA. FTIR spectra showed the main vibrational peaks of PVA/SA, with their intensity decreasing after the addition of cesium bromide. Scanning electron microscopy images showed the formation of aggregations and the increase of roughness for the PVA/SA‐CsBr NPs 15 wt% nanocomposite sample. The UV/vis. absorption spectrum showed a decrease in the energy gap values, which decreased from 4.25 to 3.89 eV in the direct transition and decreased from 4.12 to 3.77 eV in the indirect transition. Furthermore, the electrical conductivity and dielectric properties demonstrated improvement with increasing concentration of CsBr NPs. The antibacterial efficacy against Staphylococcus aureus and Escherichia coli exhibited an upward trend with an increase in CsBr nanoparticle concentration. Overall, the results suggest the promising potential of these nanocomposite films for applications in optoelectronics and biological applications.Highlights XRD shows that the amorphousity is increased after addition CsBr NPs. FT‐IR confirms the interactions/complexation between PVA/SA polymeric matrix filled with CsBr NPs. Optical energy gap is decreased with increasing CsBr concentrations. SEM images show the prepared samples have a smooth surface and only have a few defects. By adding CsBr NPs the electrical conductivity is tremendously improved.

Due to the novel physicochemical properties of polymeric nanocomposites (PNCs), a remarkable role of PNCs has been accomplished in plenty of flexible optoelectronic applications. Solution cast procedure has been performed to prepare different contents (0.1, 0.5, 1.0, 5.0, and 10 wt%) of Ag1.6Cu0.2S (ACS) incorporated in PVP/PVA blend. Fourier transforms infrared and scanning electron microscope measurements were carried out to investigate the influence of ACS on PVP/PVA structure and morphology. UV–visible spectrophotometry technique was applied to examine PVP/PVA optical properties modifications. Spectroscopic analysis reveals that direct/indirect optical bandgap of PVP/PVA host shrinks from 5.21/4.95 eV (PVP/PVA0) to 4.87/4.54 eV (PVP/PVA10). Moreover, obvious enrichments in the whole linear/nonlinear optical parameters are achieved by ACS doping. For example, refractive index and dielectric constants of PVP/PVA are increased from 1.69 and 2.87 to 1.91 and 3.63 (PVP/PVA10). While two orders of magnetite enhancement in nonlinear third‐order susceptibility are achieved via 10% ACS doping. The electrical performance of ACS PNCs has been explored, which discloses remarkable enrichments in PVP/PVA DC‐electrical conductivity () and activation energy. The obtained structural, spectroscopic and electrical investigations prove that ACS PNCs could play an efficient role in plenty of optoelectronic applications.Highlights Solution casting was used to prepare PVP/PVA loaded with Ag/CuS (ACS) NPs. FT‐IR analysis reveals successful incorporation of ACS in PVP/PVA structure. Enrichments in linear/nonlinear optical parameters are achieved by ACS doping. Electrical performance of ACS PNCs has greatly been enhanced. ACS PNCs could play an efficient role in plenty of optoelectronic applications.
