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", "download_preview_message": "", "file_order": 0, "filename": "110002290051.pdf", "filesize": [{"value": "992.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 992500.0, "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"], "permalink_uri": "http://hdl.handle.net/10191/7406", "pubdate": {"attribute_name": "公開日", "attribute_value": "2018-09-11"}, "publish_date": "2018-09-11", "publish_status": "0", "recid": "3600", "relation": {}, "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_shared_id": null}
