Cerium-containing oxide fluoride glasses CeF_3-BaF_2-AlF_3-SiO_2 were prepared under CO and Ar atmospheres. The glass prepared in CO exhibited blue emission under UV irradiation. Peak analyzes were performed to investigate their optical properties. The emission spectra were separable into three peak components by peak analysis. X-ray photoemission spectroscopy (XPS) spectra were measured to investigate the valency of the elements in the glass. Oxygen and fluorine in the glasses were more covalent and ionic than those in simple oxide and fluoride compounds. The cerium ion in the glass prepared in CO might be under a cationic condition whereas that in Ar might be under an anionic condition

“…Bezrodna et al 417 were also interested in Ti, where polydispersed anatase particles were shown to exhibit nanocrystallites containing different cations (Fe 3+ , Co 2+ and Cu 2+ ). Moving down the periodic table, Nishibu et al 418 and Kurmaev et al 419 looked at F Ka spectra in various fluorides whilst Kikas et al 420 were interested in both F 1s in LiF and O 1s in MgO crystals. This type of work reminds us of the considerable advances in instrumentation that now enable spectroscopists not only to measure these low atomic number analytes but also confidently study their peak profiles.…”

“…In fact, mineralogical effects have been used for the analysis of chemical state of elements in XRF. Shiori Nishibu et al investigate the variations of peak (Kα 1,2 ) position and relative intensity of the satellite peak of fluorine in fluorides and oxide fluoride glasses. M. Torres Deluigi et al discussed the dependence with the oxidation state of X‐ray transition energies, intensities, and natural line widths of Cr Kβ spectra.…”

Application of Kβ/Kα in selecting calibration standards for X‐ray fluorescence analysis

A method for improving the accuracy in X‐ray fluorescence spectroscopy analysis with pressed pellets was established through matching the calibration standards by the Kβ/Kα ratios. The Kβ/Kα ratios of four major elements (Al, Si, Ca, and Fe) were measured in 14 certified reference materials (CRMs) for geochemistry. The deviation of the biggest Kβ/Kα values relative to the smallest ones for the same element was from 1.52% (Si) to 20.98% (Al) when pressed pellets were used. The relative deviation of Kβ/Kα values for Ca was as high as 3.56% even for two soil CRMs (GBW07404 and GBW07408). X‐ray diffraction analysis confirmed that the Ca elements in the two CRMs were in distinct phases, thereby leading to the different Kβ/Kα values. The Fundamental Parameter Method (FPM) results of two calibration strategies were compared. When one of the 14 CRMs was selected as unknown sample whereas the other 13 CRMs were used for calibration to determine Al2O3, SiO2, CaO, and Fe2O3, the relative errors were 10.80%, 8.77%, 8.33%, and 10.91%, respectively. Another strategy, where only one CRM was used for calibration of samples with large errors, was adopted by matching Kβ/Kα values. The results of calibrating using CRM with similar Kβ/Kα values were more accurate than those with different Kβ/Kα values.
