In this study, the structural and electrical properties of TbFeO3 ceramic, prepared by the conventional mixed‐oxide reaction method, are investigated. The compound crystallizes in an orthorhombic...

2010年7月1日 · The UV/Visible absorption and XPS techniques have been used to probe the existence of Tb 3+ and Tb 4+ states. The host sensitive 4f–5d and the charge transfer transitions enabled the use of terbium ion as an indicator of the structure.

The Basic XPS Information Section provides fundamental XPS spectra, BE values, FWHM values, BE tables, overlays of key spectra, histograms and a table of XPS parameters. The Advanced XPS Information Section is a collection of additional spectra, overlays of spectra, peak-fit advice, data collection guidance, material info,

2024年9月15日 · XPS technique was employed to analyze the surface composition and electronic structure of TbCo-MOF/NF and Co-MOF/NF. XPS confirmed the existence of Tb, Co, C, N, and O elements on the TbCo-MOF/NF surface (Fig. 2 b).

2022年6月6日 · X-ray photoelectron spectroscopy (XPS) confirms the simultaneous insertion of Tb 3+ and Tb 4+ into the ZnO matrix. An increase in the Tb concentration up to 4.21% with annealing temperature is shown by energy-dispersive X-ray (EDX) measurements.

X-ray photoelectron spectroscopy was employed to ascertain the core levels of Tb 4d, Mn 2p, and S 2p. The calculated optical bandgap of the composite material was found to be 2.4 eV. Several...

X-ray photoelectron spectroscopy (XPS) confirms the simultaneous insertion of Tb³⁺... ... Tb 4+ is observed in the commercial terbium oxide TbO 1.82 , and has a binding energy of 1241.4 eV,...

2020年5月4日 · Phase formation, surface and optical studies are studied by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), ultraviolet spectroscopy and photoluminescence (PL) spectroscopy. XRD study reveals that phosphor crystallized directly to the hexagonal α-Al 2 O 3 phase at 550 ℃.

The varied chemical composition of the surface of TbMOFs and Tb x O y was investigated by X-ray photoelectron spectroscopy (XPS). X-ray diffraction (XRD) and transmission electron microscopy (TEM) revealed that aTbMOF had been fully transformed to a Tb 4 O 7 phase with a cubic crystal structure at 450 °C.
