摘要

The cerium cyclotriphosphate CeP₃O₉·3H₂O and polyphosphate Ce(PO₃)₃ have been optically investigated for the first time. In both materials, excitation and emission spectra under UV and X-ray excitations as well as emission decays of Ce³⁺ were measured at room temperature. The spectroscopic results of anhydrous Ce(PO₃)₃, prepared by progressively heating the corresponding CeP₃O₉. 3H₂O, are discussed and correlated with the structural data.
