“…The absorption band at 1044 is assigned for vibration mode of v O−C−C−O functional group (C−O stretching 1000–1100 cm −1 region) of solvent ethylene glycol as fingerprint region while band within 740–990 cm −1 range are assigned to Bi−O vibration mode frequency. The band at 1553 cm −1 indicated C=O stretching [27] . Finding of UV–visible and FTIR results are given in Table 2.…”

In this study, we have reported the synthesis of both pure and bismuth‐doped lead oxide nanoparticles using solvothermal method. The synthesized nanomaterials were analyzed to assess their structure, crystallinity, phase, maximum absorption and band gap. The electrical characteristics of the fabricated nanostructures were evaluated using cyclic voltammetry (CV) and electron impedance spectroscopy (EIS). The maximum specific capacitance and energy density, 349.96 F/g and 95.27 Wh/g respectively, were attained at a scan rate of 200 mV/s in pure lead oxide. The synthesized pure lead oxide has displayed remarkable cyclic stability, retaining approximately 83 % of its performance even after undergoing 2000 cycles. The addition of bismuth to the lead oxide appeared to inhibit the electrochemical properties of lead oxide due to bismuth ion adsorption. This effect is directly concerned with the amount of dopant which predicted the increase in bismuth contents potentially suppressed the performance of the lead oxide. Our study provides insights into the possible uses of lead oxides in energy storage and conversion devices by revealing a previously unexplored method for optimizing their electrochemical characteristics. The understanding of oxide‐based materials in materials science and electrochemistry is expected to advance with the use of this novel technology.

“…The FTIR spectra of PS/PbO composite illustrated in Figure 3 revealed the characteristic peak of the PbO band at 468 cm -1 referred to Pb-O stretching vibration, however the asymmetric bending vibration of the Pb-O-Pb bond at 686 cm -1 was overlapped and masked by the characteristic peak of PS at 694 cm -1 [40][41]. As illustrated in Figures 3 (a-c), the intensity of the PbO characteristic peak at 468 cm -1 increased with increasing PbO filler load from 10 to 35 wt% for all composites with various filler types.…”

Two different sizes of PbO nanoparticles, notably PbO(A) and PbO(B) with sizes of 78 nm and 54 nm, respectively are produced using a high-speed planetary ball milling machine under specific operating parameters. Following, the novel nanocomposite PS/PbO is synthesized using compression molding by embedding 10, 15, 25, and 35 wt% of PbO(Bulk), PbO(A) and PbO(B) into PS separately. The composite is further characterized by Fourier transform infrared spectrophotometer (FTIR), scanning electron microscope (SEM), energydispersive X-ray spectroscopy (EDS) and laser-induced breakdown spectroscopy (LIBS). FTIR results confirm the presence of PbO, and indicate a physical adsorption of the nanoparticle onto the PS matrix surface. SEM, EDS and LIBS analyses reveal a more efficient diffusion of PbO in the PS matrix with the decrease of the nanoparticle size. On the other hand, Tensile and Vickers microhardness tests are performed to investigate the composite's mechanical properties. The stiffness is, indeed, enhanced with increasing weight fraction, as well as with decreasing particle size of PbO. Whereas, the strength of the composite is optimized with 15wt% of PbO. Microhardness test reveals an ISE behavior of the composite, and an increase in H v values with PbO loads up to 15 wt%. Accordingly, by adjusting the filler particle size and concentration, the mechanical properties of the composite are evidently enhanced, increasing their use in a variety of applications such as coating, insulation and radiation shield.

“…A strong peak at 1393 cm -1 corresponds to the Pb-O stretching, and another peak at 682.9 cm -1 indicates the presence of lead [25]. The transmission peak at 460 cm -1 indicates the presence of (Pb-O) stretching vibration mode [26,27]. The peak around 833 cm -1 is due to the Pb-O vibrations, and the peak around 700 cm -1 is related to the asymmetric bending vibration of Pb-O-Pb [28] [29].…”

In this work, lead oxide (PbO) thin films were deposited using D.C. sputtering method on a surface of glass substrates and then thermally annealed at a temperature of 473K with annealing times of (1,2 and 3) hours. The structural, morphological, and optical properties of films were determined using X-ray diffraction (XRD), atomic force microscopy (AFM), FT-IR, and UV-Visible spectroscopy. The structure studies confirmed that PbO films are polycrystalline structures in an orthorhombic phase with average grain size (24.51, 29.64, 46.49, 16) nm with increasing annealing time. From AFM, the roughness of the film surface (3.26, 1.76, 1.61, 1.79) nm as the film annealing time increases. The optical band gap values of the PbO thin films are (3.9, 2.8, 3.7, 2.4) eV as the annealing time increases.
