Luminescence decay curves in e-BGO depend dramatically on the laser power; they are composed of three decay components under high-density excitation, while they show a single exponential decay at low-density excitation. From temperature dependences of the decay time and emission intensity, it is clarified that the triplet state of a self-trapped exciton (STE) responsible for the e-BGO luminescence consists of a pair of closely spaced sublevels with separation energy of 5.7 meV. The decay curves of s-BGO luminescence are essentially nonexponential, irrespective of the excitation power. Time-resolved luminescence measurements of s-BGO suggest the existence of a singlet state lying higher than the triplet STE state. The excitation spectra for the intrinsic luminescence bands have been measured up to 35 eV (35 nm) at 5 K. From the obtained spectra, it is obvious that the multiplication of electronic excitations takes place efficiently in both BGOs. The production processes of multiple excitons are discussed by referring to a recent study on the electronic structures. ©2010 The Physical Society of Japan", "subitem_description_type": "Abstract"}]}, "item_6_description_30": {"attribute_name": "資源タイプ（コンテンツの種類）", "attribute_value_mlt": [{"subitem_description": "Article", "subitem_description_type": "Other"}]}, "item_6_description_31": {"attribute_name": "フォーマット：mimeタイプ", "attribute_value_mlt": [{"subitem_description": "application/pdf", "subitem_description_type": "Other"}]}, "item_6_description_5": {"attribute_name": "引用", "attribute_value_mlt": [{"subitem_description": "Journal of Physical Society of Japan. 79:074717 (2010)", "subitem_description_type": "Other"}]}, "item_6_link_67": {"attribute_name": "WoS", "attribute_value_mlt": [{"subitem_link_text": "Web of Science", "subitem_link_url": "http://gateway.isiknowledge.com/gateway/Gateway.cgi?\u0026GWVersion=2\u0026SrcAuth=ShinshuUniv\u0026SrcApp=ShinshuUniv\u0026DestLinkType=FullRecord\u0026DestApp=WOS\u0026KeyUT=000280096900048"}]}, "item_6_publisher_4": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Physical Society of Japan"}]}, "item_6_relation_48": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "10.1143/JPSJ.79.074717"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1143/JPSJ.79.074717", "subitem_relation_type_select": "DOI"}}]}, "item_6_rights_62": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "©2010 The Physical Society of Japan"}]}, "item_6_select_64": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_6_source_id_35": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0031-9015", "subitem_source_identifier_type": "ISSN"}]}, "item_6_source_id_39": {"attribute_name": "NII ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0031-9015", "subitem_source_identifier_type": "ISSN"}]}, "item_6_source_id_40": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00704814", "subitem_source_identifier_type": "NCID"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Itoh,  M"}], "nameIdentifiers": [{"nameIdentifier": "38259", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Katagiri,  T"}], "nameIdentifiers": [{"nameIdentifier": "38260", "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": "2015-09-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "JPSJ.pdf", "filesize": [{"value": "690.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 690100.0, "url": {"label": "JPSJ.pdf", "url": "https://soar-ir.repo.nii.ac.jp/record/12523/files/JPSJ.pdf"}, "version_id": "613b6f29-2861-44a0-8218-f0838dd6b24d"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "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": "Intrinsic Luminescence from Self-Trapped Excitons in Bi4Ge3O12 and Bi12GeO20: Decay Kinetics and Multiplication of Electronic Excitations", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Intrinsic Luminescence from Self-Trapped Excitons in Bi4Ge3O12 and Bi12GeO20: Decay Kinetics and Multiplication of Electronic Excitations", "subitem_title_language": "en"}]}, "item_type_id": "6", "owner": "1", "path": ["1222"], "permalink_uri": "http://hdl.handle.net/10091/10296", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2010-09-08"}, "publish_date": "2010-09-08", "publish_status": "0", "recid": "12523", "relation": {}, "relation_version_is_last": true, "title": ["Intrinsic Luminescence from Self-Trapped Excitons in Bi4Ge3O12 and Bi12GeO20: Decay Kinetics and Multiplication of Electronic Excitations"], "weko_shared_id": -1}
