“…The absorption band peaking at about 245 nm in C0Y1 could be ascribed to the charge transfer state (CTS) of Yb 3+ [9]. With the adding of Ce 3+ , the absorption edges of the phosphate glass samples shift from 210 nm to 310 nm, which is in accordance with the Ce 3+ absorption peak (about 314 nm) [10]. decay rate.…”

“…Rare earth ions like Ce show shake‐up satellites in the main photoelectron peak. In the case of Ce +4 three satellites can be identified together with a third peak located at ~916 eV . Curve fitting of Ce 3d spin orbit doublet was performed.…”

Germanate glasses have potential applications as optical fibers. Materials doped with rare earth ions are good candidates for optical, lasing, and magnetic applications. Based on the ternary system, CeO 2 -Na 2 O-GeO 2 a series of six glasses were fabricated using powder fusion, and varying the Na 2 O content from 0 to 45 mol%, and a CeO 2 content constant at 3 mol%. The glasses were analyzed by FT-IR, Raman and X-ray photoelectron (XPS) spectroscopies to obtain information about the glass structure, cerium oxidation's state and how it is introduced in the glass network. FT-IR and Raman spectra revealed the presence of GeO 6 and GeO 4 groups as well as Q 2 and Q 3 units in the glasses with alkali low content. XPS spectra analysis revealed that the cerium ions were reduced from Ce 4+ to Ce 3+ . The nonbonding to total oxygen ratio was estimated from the curve fitting of the O 1s core level spectra. Density and elastic parameters showed a nonlineal tendency in the change of the physical properties as a function of Na 2 O content. Finally, photoluminescence spectroscopy confirmed the presence of Ce 3+ ions. The characteristic 4f ? 5d electronic transitions at 360 nm were detected, when a 280 nm excitation line of pulsed laser was used as excitation source.

“…Cerous (Ce 3+ ) and ceric (Ce 4+ ) cations have absorption bands, at 314 and 240 nm, respectively in silicate glasses, which provide glasses with strong UV absorption while remaining visibly colorless . The synthesis and properties of cerium‐doped aluminosilicophosphate glasses were recently reported . It was shown that, compared with cerium‐doped silicates, the phosphate UV absorption edge is blue‐shifted and the cerium‐content can be >16 times higher with similar visible coloration.…”

The local structure of cerium in two systematic compositional series of glasses, nominally CeP 3 O 9 -AlP 3 O 9 and CeP 3 O 9 -SiP 2 O 7 , was interrogated using X-ray photoelectron spectroscopy (XPS) and X-ray absorption fine structure (XAFS) spectroscopy. XPS revealed that, for glasses melted in air, ! 95% of cerium ions are Ce 3+ . This was independently confirmed using X-ray absorption near edge spectroscopy (XANES). Ce K-edge extended X-ray absorption fine structure (EXAFS) has been used to determine the local structure of Ce 3+ . Near the metaphosphate composition, cerium was found to have an average cerium coordination number of~7.0 and an average cerium-oxygen bond length of 2.41 Å . The average cerium coordination number and average cerium-oxygen bond distance were found to increase with decreasing cerium concentration in both compositional series. Rare-earth clustering is suggested based on numerical calculations for glasses containing ! 14 and ! 15 mol% Ce 2 O 3 for the aluminophosphate and silicophosphate series, respectively. II. BackgroundTwo compositional series, centered on cerium metaphosphate, Ce 2 O 3 ·3P 2 O 5 , were chosen to investigate cerium incorporation L.-Q. Chen-contributing editor Manuscript No. 28744.
