Abstract
Polyvinyl Alcohol (PVA) of PVA-3%M, where M stands for NiO, MgO, and Al2O3, has been created. Characterization was done using X-ray diffraction (XRD). This characteristic verified the production of the generated oxide NPs during chemical precipitation in PVA. The PVA-3% M nanoparticles (M=NiO, MgO, and Al2O3) were examined for their optical characteristics. After 60 minutes, the PVA-3% M nanoparticles (M=NiO, MgO, and Al2O3) were subjected to UV light irradiation to examine its effects. The optical properties have been studied in UVA (315–400 nm) area, or long-wave UV, in energy of (3.9–3.1) eV. Time under UV light has an impact on the optical energy gap of PVA-3% M. As a function of the UV exposure time, the optical characteristics of PVA3% M nanoparticles (M=NiO, MgO, and Al2O3) were evaluated. Calculated optical constants for PVA-3% M (M=NiO, MgO, Al2O3) NPs as-prepared and after UV irradiation illustrate the impact of UV irradiation period. These data demonstrate that a highly forced for medical applications.
