“…The data obtained by this technique are used to calculate the band gaps of semiconductors using the following Kubelka–Munk function 27 :

\begin{equation*}F\ \left( R \right) = \frac{{{{\left( {1 - R} \right)}}^2}}{{2R}}\ = \frac{K}{S}\end{equation*}

where R is the diffuse reflectance of the sample, and K and S represent the absorption and scattering coefficients. The band gap energy ( E g ) of the semiconductor sample can be determined by linear plotting of [ F ( R ) hʋ ] 2 versus hʋ .…”

In this study, as‐prepared and Ag‐decorated ZnO/Zn(OH)2 composite nanoparticles (NPs) were obtained using the sol–gel technique. First, the effect of aging on the structural, optical, and morphological features was examined. Ag NPs can interact with the electronic structure of ZnO/Zn(OH)2 NPs, resulting in changes in their energy levels. It was found that the composite NPs obtained after 6 h solution aging increased in full width at half maximum and good crystallinity of the structures from the X‐ray diffraction (XRD) measurements. The Raman spectrum supports the experimental data obtained from XRD and Fourier transform infrared, a material containing a mixture of ZnO and Zn(OH)2. From the morphological study, Ag NPs were successfully decorated on the ZnO/Zn(OH)2 surface, and composite NPs did not change the morphological appearance of the structure. Second, the photocatalytic performance of the samples was investigated. In the experimental setting, ultra‐violet A light was employed as the irradiation source, whereas rhodamine B (RhB) was used as the dyestuff. The photo‐degradation of the RhB dyestuff on composite NPs was observed to be 98.5% and 92.5% for 6 and 2 h aged samples, respectively. On Ag NPs, the catalytic performance of the sample was increased up to 95% after 180 min.

The importance of polymeric additives has taken an important role in industrial technology and its development and the increase in the consumption period of industrial products, especially plastic products. Therefore, a different type of polymeric additive was used, which can be classi ed as another type of polymeric additive, where three types of polymers were synthesized as polymeric additives. These polymers differ from each other only in stereo geometry. Three geometric shapes of the polymer were synthesized, namely, ortho, meta, and para polymers. They were studied as photo stabilizers for PVC and compared as the best photostabilizer for PVC. Polyorganosiloxane was invented by various technologies. Polyorganosilanes and poly(vinyl chloride) (PVC) were combined to create homogeneous lms. Various methods were used to investigate the effects of long-term irradiation on polyorganosilane-containing lms. The development of side products containing polyene and carbonyl groups was observed in the infrared spectra of PVC lms before, during, and after irradiation. The absorption bands' intensities of the functional groups associated with the polyorganosilanes were lower when it was present. Furthermore, it was observed that the weight of PVC lms dropped less when irradiating them after hybridization with polyorganosilanes. In the presence of polyorganosilanes, there was also a minor alteration in the surface of irradiated PVC. Photodegradation of PVC is inhibited by polyorganosilanes. Hence, the role of polyorganosilanes to stabilize PVC against UV exposure has been studied.
