A luminescent complex species having 1 : 3 stoichiometry was formed at pH 8.4〜11.6. Those complexes were hydrolyzed by more alkaline solution. The relative quantum yield of Tb(III)-CDA complex at PH 11.6 was 0.636 (λ_<em>=544 nm) on a quinine sulfate basis. The luminescence lifetimes of Tb(III)-CDA were calculated as 1.02 ms at pH 8.4 and 1.55 ms at pH 11.6. The luminescence intensities of Tb(III) and Eu(III)-CDA complexes increased from pH 9 to 11 with the deprotonation degree of the 4-hydroxyl group on the complexes. The deprotonated Ln(III)-CDA complex species possibly has a resonance structure of the pyridone type, which would contribute to the highly enhanced luminescence intensity. Detailed photophysical data in terms of photoexcitation and the triplet energy level (low temperature phosphorescence) are given.","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_other_language_22":{"attribute_name":"その他の言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人日本分析化学会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05251931","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"TAKAHASHI, Nobuyuki"},{"subitem_text_value":"SAITO, Shingo"},{"subitem_text_value":"HOSHINO, Hitoshi"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002492"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"東北大学大学院環境科学研究科"},{"subitem_text_value":"北見工業大学工学部"},{"subitem_text_value":"東北大学大学院環境科学研究科"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Environmental Studies, Tohoku University"},{"subitem_text_value":"Kitami Institute of Technology"},{"subitem_text_value":"Graduate School of Environmental Studies, Tohoku University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2003-9"}]},"item_119_version_type_28":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高橋, 伸幸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"齋藤, 伸吾"},{"creatorName":"サイトウ, シンゴ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"星野, 仁"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1002492.pdf","filesize":[{"value":"340.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002492.pdf","url":"https://sucra.repo.nii.ac.jp/record/13149/files/A1002492.pdf"},"version_id":"053e749d-79df-4856-b94d-9fc5a065b27c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"energy-transfer luminescence","subitem_subject_scheme":"Other"},{"subitem_subject":"terbium","subitem_subject_scheme":"Other"},{"subitem_subject":"europium","subitem_subject_scheme":"Other"},{"subitem_subject":"complex","subitem_subject_scheme":"Other"},{"subitem_subject":"chelidamic acid","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"4-ヒドロキシピリジン-2,6-ジカルボン酸-ランタノイド（III）錯体の生成反応とエネルギー移動発光挙動","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"4-ヒドロキシピリジン-2,6-ジカルボン酸-ランタノイド（III）錯体の生成反応とエネルギー移動発光挙動"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-03-12"},"publish_date":"2008-03-12","publish_status":"0","recid":"13149","relation_version_is_last":true,"title":["4-ヒドロキシピリジン-2,6-ジカルボン酸-ランタノイド（III）錯体の生成反応とエネルギー移動発光挙動"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T19:06:11.893544+00:00"}
