Rapid NO2 gas sensor has been developed based on PbS nanoparticulate thin films synthesized by Successive Ionic Layer Adsorption and Reaction (SILAR) method at different precursor concentrations....
Lead Spectra – Pb metal – The International XPS Database 1
The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.
XPS spectra of Pb ion before (a) and after (b) hydrogen reduction
The XPS of Pb 4f spectrum exhibits spin orbit splitting peaks of Pb 4f 7/2 and Pb 4f 5/2 at 138.9 and 143.8 eV, respectively, and the lead ion keeps in the state of Pb 2+ .
XPS-and-DFT analyses of the Pb 4f - ScienceDirect
2017年5月31日 · The electronic structures of zincite Pb-modulated bulk and thin-films were studied via X-ray photoelectron spectroscopy (XPS) and density functional theory (DFT) techniques. Both XPS data and DFT-calculations allowed the derivation of two different Pb-embedding scenarios into the ZnO-hosts.
