High-sensitive XANES analysis at Ce L2-edge for Ce in bauxites using transition-edge sensors: Implications for Ti-rich geological samples

Spin dynamics phenomena of a cerium(iii) double-decker complex induced by intramolecular electron transfer

“…A white-line peak for the Ce 3+ state appears at 5726 eV (labeled as a), which is associated with the 2p → 4f 1 5d dipole-allowed transition. 55,56,89 For 1 and 2 , a white-line peak appeared at 5726 eV at the same energy as the white line of CeCl 3 . However, the feature in spectra of 1 and 2 was slightly broader than that of CeCl 3 .…”

Tunable valence state and scintillation performance of dense Ce3+-doped borosilicate glasses prepared in ambient atmosphere

“…Moreover, CeO 2 shows a Ce 4+ oxidation state with two peaks at 5734 eV and 5741 eV, corresponding to 2p 3/2 -(4f 1 L)5d and 2p 3/2 -(4f 0 )5d transitions, respectively. 16,17 When x = 0, the XANES spectrum of GABS 0 glass shows Ce 4+ characteristics, and there is a large amount of Ce 4+ in the glass. Other GABS x glasses exhibit characteristics of the Ce 3+ ion spectrum, indicating that Si 3 N 4 as a reducing agent can effectively control the valence state of cerium.…”

Development of High-Energy µ-X-ray Fluorescence and X-ray Absorption Fine Structure for the Distribution and Speciation of Rare Earth Elements in Natural Samples

“…The primary aim of this study is to extend the µ-XRF-XAFS analysis to K-edges of REEs (up to Dy) to avoid possible interferences that occur when using L-edges and L lines without state-of-the-art high-energy resolution detectors such as the crystal analyzer system [19] or transition-edge sensor (TES) detector [37]. For this purpose, the KB mirror applicable to HER was used to obtain submicron X-rays.…”
