Nio Xps

Xps spectra were measured with the physical electronics model 5400 x ray photoelectron spectrometer using unmonochromatized mg k α x rays at two pass energy settings corresponding to analyzer energy resolutions of 1 34 and 0 54 ev.

Nio xps. Detailed examination of the ni 2p and o 1s regions reveals that hydroxylation upon prolonged exposure to the ambient causes a noticeable change in the ni 2p peak shape that could be misinterpreted as an artifact of particle size. Cleaving an extra feature at 2 0 ev lower binding energy begins to develop. The results show the phase of the ni nio pdda g and the loading content of ni nio is about 35 wt. Satellite features not to be confused with oxidized nickel peaks.

We report x ray photoemission spectra xps of nickelous oxide nio. Collecting chemical information from the top 1 10nm of materials ranging from metals to polymers to organic thin films. In xps spectra the well known satellite 6 ev above the main emission line. Ni compounds can also have complex multiplet split peaks.

Ni2p peak has significantly split spin orbit components δ metal 17 3ev. A ni 2p xps of a freshly cleaved nio 100 single crystal at dilierent polar angles as indicated. Ni2p3 2 x ray photoelectron spectral peak binding energies of ni metal nis and nias all conductors span a range of about 0 5 ev and are consequently insensitive to formal ni oxidation state and to the nature of the ligand to which ni is bonded relative to other metals e g fe. The morphologies and chemical composition of ni nio pdda g were evaluated by tga xrd tem and esca xps.

Learn how our line of xps systems fits your application. In this data in brief article dataset of plasma assisted nitrogen doping of a binderless spin coated cuo nio mixed oxide thin film was presented 21. Mixture of core level and satellite features. Using xps depth profiling we investigated the nio x overstoichiometry x 1 in the films that was found by other methods and the chemical changes in the films during annealing.

Ni2p3 2 peak structures and binding energies reflect two energetic contributions. Explore our information packed knowledge base of elemental properties and xps analysis. This behaviour is intensified when the crystal is sputtered. Beginning with nickel metal els they suggest that more intense features at 6 0 and 9 5 ev are due to surface and bulk plasmon losses respectively with weaker intra and in ter band transitions at 3 7 and 7 1 ev.

B ni 2p xps oi a soilly sputtered nio lo0 single clystal at different polar angles as indicated. The cv and eis results of ni nio pdda g in 0 5 m aqueous h 2 so 4 are better than those in 0 5 m aqueous h 2 so 4 0 5 m ch 3 oh. Interpretation of xps spectra.
