In this work, Sn and Ag doped PbS/PVA nanocomposites, in three different concentrations were successfully prepared using the low-cost and simple method of chemical bath deposition (CBD). X-ray...

2019年5月29日 · The mechanism of magnesiation/demagnesiation in CuS NPs has been probed by X-ray photoelectron spectroscopy (XPS) and energy-dispersive X-ray spectroscopy (EDX).

2017年5月30日 · The oxidation state of Cu and S in the as-prepared bulk CuS was analyzed by XPS. The high resolution XPS spectra of the Cu 2p and S 2p core levels for the CuS (covellite) was displayed in...

2025年2月10日 · In the XPS spectrum of the S 2p peak (Fig. 3c), the binding energies at 161.18 eV and 162.78 eV were, respectively, assigned to S 2p 3/2 and S 2p 1/2. Figure 3d shows XPS spectra of Cu 2p peaks of the CuS/SnS 2 @CC, the peaks associated with Cu 2p 3/2 and Cu 2p 1/2 were observed

XPS 光谱解读. Cu2p 峰具有明显的自旋轨道分裂峰 (Δ=19.75 eV，强度比=0.508) 根据 Cu2p 的卫星特征峰能区分铜的氧化态。 二价铜在 943 eV 处可观测到一组卫星特征峰。 氧化铜的 Cu2p3/2 峰有位移，其峰宽大于氧化亚铜峰。

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.

We report the first thermoelectric properties of Cu1-xAgxS, x = 0-0.75 nanocomposites, synthesized by using a facile polyol method.
