However, the AG mechanism has not been clarified yet. In this study, the long-lasting AG mechanism of SrArAl_2O_4 phosphors doped with Eu and/or Dy, was investigated on the basis of AG, photoluminescence (PL), and thermoluminescence (TL) measurements after UV or X-ray irradiation. A hole trap is presumed to be ascribed to Sr defects, which increases and is stabilized by a charge compensation behavior upon doping Dy ion. An electron trap probably originates from oxygen defects, as produced by firing in a reductive atmosphere. Furthermore, the role of dopants (Eu, Dy ion) on SrAl_2O_4 phosphor co-doped with Eu and Dy ions, was studied by comparing the luminescence (AG and PL) phenomena with the distribution of dopant in SrAl_2O_4 matrix. Eu ion contributed closely to both the AG and PL behaviors, while the Dy ion contributes only to the AG phenomenon.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"43937","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ohta, Masatoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"43938","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Maruyama, Mizuho"}]},{"nameIdentifiers":[{"nameIdentifier":"43939","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hayakawa, Takayoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"43940","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nishijo, Tomohiko"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本セラミックス協会"}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002290051","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本セラミックス協会"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10040326","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09145400","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"太田, 雅壽"}],"nameIdentifiers":[{"nameIdentifier":"43933","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"丸山, みずほ"}],"nameIdentifiers":[{"nameIdentifier":"43934","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"早川, 陽喜"}],"nameIdentifiers":[{"nameIdentifier":"43935","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西條, 智彦"}],"nameIdentifiers":[{"nameIdentifier":"43936","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-30"}],"displaytype":"detail","filename":"110002290051.pdf","filesize":[{"value":"992.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110002290051.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/3600/files/110002290051.pdf"},"version_id":"507b8ff4-a8bb-407c-87fa-e6d7e84cb7d1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Long-lasting afterglow","subitem_subject_scheme":"Other"},{"subitem_subject":"Photoluminescence","subitem_subject_scheme":"Other"},{"subitem_subject":"Thermoluminescence","subitem_subject_scheme":"Other"},{"subitem_subject":"Strontium aluminate","subitem_subject_scheme":"Other"},{"subitem_subject":"Europium","subitem_subject_scheme":"Other"},{"subitem_subject":"Dysprosium","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":"長残光アルミン酸ストロンチウム蛍光体における付活剤の役割","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"長残光アルミン酸ストロンチウム蛍光体における付活剤の役割"},{"subitem_title":"長残光アルミン酸ストロンチウム蛍光体における付活剤の役割","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-09-11"},"publish_date":"2018-09-11","publish_status":"0","recid":"3600","relation_version_is_last":true,"title":["長残光アルミン酸ストロンチウム蛍光体における付活剤の役割"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:41.688204+00:00"}
