The assay of PbO-NPs optical features was provided by the results of UV-Vis spectrophotometry, while the XRD patterns approved their tetragonal and orthorhombic crystallized structures.

2017年10月13日 · We investigated the electronic structure of Lead Oxide (PbO) – one of the most promising photoconductor materials for direct conversion x-ray imaging detectors, using soft x-ray emission and ...

The XRD patterns of the samples exhibit that the main phase is LiFePO4 with minor impurity phases of PbO and Fe2O3 in the structure, in which the phase ratio of PbO increases with increasing...

1984年11月1日 · X-ray diffraction pattern for typical battery oxide and NaF mixture (NaF weight fraction, 0.2). An XRD pattern for a typical battery oxide and internal standard mixture is presented in Fig. 2, relevant a-PbO, ss-PbO, Pb, and NaF peaks being indicated.

Their structural parameters, morphology, and chemical bonds, were investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM), and Fourier-transform infrared spectroscopy...

2009年7月6日 · The present study reports the preparation and characterization of PbO nanocrystals obtained via a thermal decomposition route. The PbO nanocrystals were synthesized using lead oxalate powder as a precursor. Nanostructured products were investigated by means of XRD, TEM, FT-IR and XPS.

2014年5月15日 · PbO 2 particles with multiple morphologies and phases were chemically synthesized. The electrode made with β-PbO 2 and α-PbO 2 (1:1) displays better electrochemical performance. The electrode can deliver a capacity of 183 mA h g −1 at 0.1 C after 100 cycles. The pretreated electrode displays improved stability of cycle.

2007年6月16日 · Litharge, the red tetragonal form of lead oxide α-PbO and massicot, the yellow orthorhombic form β-PbO, are synthesized from lead (II) salts in aqueous media at elevated temperatures. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to characterize the size, morphology, and crystallographic structural forms of the products.

2011年11月22日 · Carbon fibers, obtained by carbonizing poly(p-phenylene benzobisoxazole) (PBO) fibers at 900 °C, graphitize extensively upon heat treatment at higher temperatures (2700 °C). In this work, XRD, Raman spectroscopy, and HRTEM are used to monitor the structural and nanostructural transformations of the carbon material under heat-treatment at ...
