2013年4月1日 · XPS results indicated that Zn 2p lines in ZnO nanorods have highest binding energy. Also, the optical properties of three morphologies of ZnO nanostructures were analyzed and confirmed that crystallites of bigger sizes have smallest value of energy band gap.

2023年7月3日 · X-ray photoelectron spectroscopy (XPS) is widely used to determine the chemical and electronic states of atoms within a material. However, it is often complex to interpret the O 1s region in metal oxides, where an ∼531 eV binding energy feature appears between lattice oxygen (∼530 eV) and oxygen-containing surface species (∼532 eV).

Zinc oxide (ZnO) nanorods and ZnO nanostructures composited with silver (Ag) and multi-walled carbon nanotubes (MWCNTs) have been synthesized by a simple impregnation–calcination method and...

2017年11月8日 · Emission/absorption in the UV and visible-region by ZnO nanostructures were investigated via analyzing defects states (vacancies, interstitials and antisite) in the studies conducted by PL and...

Fig. 7 demonstrates the comparison of raw data of high resolution XPS spectra of the Zn 2p region (I) and O 1s core-level (II) of various morphologies of ZnO (a) nanoparticles, (b) nanoflowers...

Structural and optical characterizations of synthesized ZnO NPs were thoroughly probed applying X-ray diffraction (XRD), transmission electron microscope (TEM), energy dispersive X-ray (EDX)...

2025年2月27日 · In the O 1s XPS spectrum of Fig. 6 (b), a significant characteristic peak at 529.6 eV is observed for ZnO, which corresponds to the bonding between Zn and O in ZnO. After the addition of the organic material PDI-C8, the original O 1s peak disappears, leaving only a reduced peak at around 531.4 eV.

2025年2月28日 · XPS analysis reveals the chemical composition and surface states of the nanostructured ZnO. Figure 2a shows the full-survey XPS spectra, which indicate the presence of only Zn, O, and C, thus confirming the pure formation of the prepared nanostructured ZnO. 22 Figure 2b shows the peaks of the Zn 2p 3/2 and Zn 2p 1/2 states; the binding energy ...

The film composition and electronic structure were investigated by X-ray photoelectron spectroscopy (XPS). The measurements were performed on a VG ESCALAB II system using MgKα radiation with energy of 1253.6 eV.

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.
