+、50MeVのHe2 +、および220MeVのC5 +のパルスイオンビームを用いて得られた。 GAGGの発光の立ち上がり速度はLETが低いほど減少し、発光減衰速度はLET依存性がないことが分かった。 このGAGGの発光の立ち上がり速度は、発光中心であるCe 3+イオンへのエネルギー移動速度に対応すると考えられる。 GAGGへのイオンビーム照射におけるゆっくりとした発光の立ち上がりは、Ce 3+イオンへのエネルギー移動により複数の励起状態が競合して存在していることが考えられる。","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.nimb.2018.10.045","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/pii/S0168583X18306384","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0168-583X","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata
