Abstract
- Abstract: Cerium-containing oxide fluoride glasses CeF3–BaF2–AlF3–SiO2 were prepared under CO and Ar atmospheres. The glass prepared in a CO atmosphere exhibited blue emission under UV irradiation because the hydrolysis of CeF3 to a Ce4+-containing compound during heating process was controlled. The emission spectrum was separable into three peak components by peak analysis. X-ray photoelectron spectroscopy (XPS) spectra were measured to investigate the valency of the elements in the glass. Oxide and fluoride ions in the glass respectively have different electronic states from those in CeO2 and CeF3. The electronic state of cerium ion in the oxide fluoride glass differed from that in CeO2 and CeF3. [Copyright &y& Elsevier]
