“…Specifically for the Co-doped α-PbO, an induced strain increases more when compared with other doped materials; inversely, the crystallite size of Co-doped α-PbO decreases more, which shows a huge influence of crystalline quality. The substantial difference in the radii of Co 2+ with the host Pb 2+ and O 2− which is s 0.135 nm, 0.119 nm, and 0.065 nm respectively is the main reason for the substantial induced strain in Codoped α-PbO [38]. Thus, the Co-doped is added as an impurity into the materials in interstitial form rather than occupying the site of the host atom.…”

In recent days, metallic oxide semiconductor nanoparticles have drawn attention to the photocatalytic degradation of organic pollutants. In the present work, undoped and different metals (Sn, Co, Cu, Ni, and Li)-doped of α-PbO nanoparticles were successfully synthesized by a facile chemical precipitations method. The obtained nanoparticles were further studied by using different characterization techniques. The XRD results confirmed that the prepared nanoparticles were a tetragonal, α-PbO phase crystal structure without mixing other PbO phases. The obtained optical band gaps from UV-Vis DRS analysis were 2.03 eV, 2.68 eV, 1.61 eV, 1.78 eV, 1.67 eV, and 2.00 eV for pristine α-PbO, Sn, Co, Cu, Ni, and Li doped α-PbO respectively. From the PL emission, the lowest PL intensity of the doped samples indicated the low recombination of the electron-hole pairs that improved the photocatalytic performance of pristine α-PbO. SEM and EDX were used to analyze the surface morphology and composition of the synthesized nanoparticles, respectively. The photocatalytic activities of the prepared nanoparticles were assessed through the degradation of the Methylene Blue (MB) dye under visible light irradiation. The UV-Visible spectrophotometer analysis showed that the MB dye concentration decreased as the irradiation time varied from 20 to 100 min. The results showed that within 100 minutes, the Sn-doped α-PbO nanoparticles possessed the maximum degradation efficiency compared to other metal-doped α-PbO nanoparticles, with 100 % MB dye degradation compared to 94.76 % by pristine α-PbO. This was due to the increased visible light harvesting, which aided in the photocatalytic degradation of MB dye.

Aluminum‐doped ZnO (AZO) were successfully prepared on polyimide (PI) film using electrochemical deposition. Field emission scanning electron microscopy (FESEM) analysis revealed that as the aluminum concentration increased, the morphology of AZO nanostructures changed from pellets to nanorods. X‐ray photoelectron spectrometry (XPS) was employed to study the chemical states of undoped and Al‐doped ZnO on a polyimide substrate. The X‐ray diffraction (XRD) patterns of the PI/AZO nanostructures showed a polycrystalline wurtzite structure with a crystallographic orientation along the (002) plane. The XRD analysis also indicated that the average crystallite size decreased from 50.5 nm to 31.0 nm with increasing aluminum concentration (from 0.05 mM to 10 mM). Transmittance analysis revealed that with increasing aluminum concentration, the average optical transmittance in the visible region decreased from 90 % to 75 %. The aluminum concentration has a significant effect on the electrical properties of the samples, as shown by current‐voltage (I–V) and Hall measurements. Among the samples, the AZO/PI film prepared with 5 mM aluminum concentration exhibited the minimum electrical resistivity (4.14×10−2 Ω.cm), the highest carrier density (1.10×1021 cm−3) and the Hall mobility (5.40 cm2 V−1 s−1). We also discuss the possible mechanisms underlying these results compared to undoped ZnO films. This study contributes to the potential applications in flexible electronics and optoelectronics by demonstrating the tunability of AZO nanostructures on a flexible polyimide substrate through controlled aluminum doping.
