ラマン分光測定は酸素空孔や化合物の分析手法として広く使用されているが、酸素不定比性を有するアクチノイド酸化物のラマンスペクトルデータは非常に少ない。したがって、本研究では不定比組成の(U$$_{1-y}$$Ce$$_{y}$$)O$$_{2}$$のラマンスペクトルの取得と解析を目的とした。その結果、定比組成及び不定比組成の(U$$_{1-y}$$Ce$$_{y}$$)O$$_{2}$$のラマンスペクトルを取得することに成功した。また、T$$_{2g}$$ピークはCeO$$_{2-x}$$と同様のピークシフト挙動を示すことがわかった。

Raman spectroscopy has been widely used to detect the oxygen vacancies and proven to be a very powerful characterization technique. The Raman spectral data of non-stoichiometric actinide oxides are very limited. The purpose of this work was to measure the Raman spectra of a non-stoichiometric (U$$_{1-y}$$Ce$$_{y}$$)O$$_{2}$$ solid solution. The Raman spectra of stoichiometric and non-stoichiometric (U$$_{1-y}$$Ce$$_{y}$$)O$$_{2}$$ are successfully measured. The T$$_{2g}$$ peak of non-stoichiometric (U$$_{1-y}$$Ce$$_{y}$$)O$$_{2}$$ exhibited the same peak shift behavior as hypo-stoichiometric CeO$$_{2}$$.
