Virgin and Yb-implanted epitaxial ZnO films grown using atomic layer deposition (ALD) were investigated by X-ray absorption spectroscopy (XAS). XAS study revealed a strong polarization...

2004年11月18日 · absorption spectroscopy (XAS) and emission spectroscopy (XES) were performed to study the electronic structure of nanostructured ZnO. The band gap is determined by the combined absorption-emission spectrum.

2022年3月15日 · Soft X-ray absorption spectromicroscopy (XAS) gives insight for Zn electrochemistry. Zn anode cycling in mildly acidic aqueous electrolyte can generate zincates. Parasitic HER yields space distribution of Zn species in mildly acidic electrolyte. Chemical-state distribution of discharged and cycled Zn anodes, disclosed by XAS.

2021年5月31日 · To this end, we have used combined x-ray diffraction (XRD) and x-ray absorption spectroscopy (XAS) at the Zn K-edge to monitor the process of converting crystalline ZnO 2 to ZnO during a thermal decomposition process. XRD provides information regarding long-range order (crystallinity) whilst XAS (an element specific technique that does not ...

2006年8月1日 · The electronic structures of ZnO nanoparticles and microrod arrays are studied by O 1s X-ray absorption spectroscopy (XAS) and O Kα X-ray emission spectroscopy (XES). We show that the present LDA+U SIC calculation approach is suitable to correct the LDA self-interaction error of the cation d-states.

ZnO is Wurtzite structured and crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Zn2+ is bonded to four equivalent O2- atoms to form corner-sharing ZnO4 tetrahedra. There are three shorter (2.00 Å) and one longer (2.01 Å) Zn–O bond lengths.

2022年9月5日 · Our study on Sm-substituted ZnO nanomaterials is reported with Rietveld-refined X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), UV–Vis-NIR spectroscopy, Raman spectroscopy and Zn L 3,2, Sm M 5,4 and O K edge X-ray absorption spectroscopy (XAS) to correlate the defect structures and consequent oxygen vacancies w...
