Influence of binding effects in cerium materials for Lq (q = l, η and α1,2) X-ray emission spectra

The current investigation illustrates the systematic interrogation of the energy changes in the L-q (q = l, eta and alpha(1,2)) X-ray peaks of distinct cerium (Ce) materials by employing a wavelength-dispersive spectrometer. The present work counsel's valuable information for deep insight about the local structure and binding energy effects in distinct cerium materials viz., CeX [X = Cl-3, F-3 and O-2] and Ce2S3O12 on the L-q (q = l, eta and alpha(1,2)) X-ray lines. The present finding reveals that the L-q (q = l, eta and alpha(1,2)) X-ray lines emanated from different Ce materials show energy shifts of similar to 1.67-7.62 eV concerning the pure Ce target. A procedure for estimating measured and calculated radiative L3M transition probabilities for distinct Ce materials has been in-corporated at present assessment, assuming the different sets of natural line widths for the L-shell hole states, prominent to statistical dissemination of particular initial states. Additionally, the measured values of relative intensity ratios I-Q [Q = Ll/L alpha(1,2) and L eta/L alpha(1,2)] for Ce materials show higher discrepancies relative to pure Ce which can be imitated in the perspective of change in the crystal structures, different electronegativity of the adjacent ligands attached to Ce+3 or Ce+4 ions and influence of outermost screening constants. The promising connection among energy shifts in Ce L-q (q = l, eta and alpha(1,2)) X-ray lines of different materials and influencing parameters are also explored in this work. (C) 2021 Elsevier B.V.
