In (Y1−x Tb x )4(SiS4)3, the green photoluminescence band corresponding to the intra 4f transition of 5D4  →  7F5 appears at 545 nm and becomes the maximum for x  =  0.2 in the range x  =  0.01 to 1. The internal quantum efficiency is higher (11% for x  =  0.01) for the thiosilicate host excitation (360 nm) than for the direct excitation (1.6%) of the intra 4f transition of 5D4  ←  7F6 (489 nm). A time-resolved photoluminescence study shows that the luminescence of defect states of thiosilicate hosts decays faster (typically 10–30 ns) for higher Tb3+ concentration x. In addition, the rise time of Tb3+ photoluminescence is shorter (10–40 ns) for greater x. Energy transfer from the thiosilicate host to Tb3+ is discussed using these results. For all of (Y1−x Ln x )4(SiS4)3 (x  =  0.01, Ln  =  Pr, Nd, Dy, Er or Tm), the internal quantum efficiency is higher for the host excitation (11–21%) than for the direct excitation of intra 4f transitions (1.1–12%). A photoluminescence excitation study reveals broad host absorption in 300–400 nm for Ln luminescence. These results show the promising characteristics of the host absorption of (Y1−x Ln x )4(SiS4)3 phosphors and their optical properties.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/0022-3727/49/10/105103","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1088/0022-3727/49/10/105103","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2016 IOP Publishing Ltd Printed in the UK "}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0022-3727","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nanai, Yasushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suzuki, Yousuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okuno, Tsuyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-04-03"}],"displaytype":"detail","filename":"20190403uecripojitoriLa6Si4S17_draft_revised_ver180207.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20190403uecripojitoriLa6Si4S17_draft_revised_ver180207","url":"https://uec.repo.nii.ac.jp/record/9052/files/20190403uecripojitoriLa6Si4S17_draft_revised_ver180207.pdf"},"version_id":"d204d6a7-f7f1-4e09-a798-5f25e17f627c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"lanthanide","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"luminescence","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"phosphor","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sulfide","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"thiosilicate","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Efficient host excitation in thiosilicate phosphors of lanthanide(III)-doped Y4(SiS4)3","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Efficient host excitation in thiosilicate phosphors of lanthanide(III)-doped Y4(SiS4)3","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"13","path":["6"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-04-03"},"publish_date":"2019-04-03","publish_status":"0","recid":"9052","relation_version_is_last":true,"title":["Efficient host excitation in thiosilicate phosphors of lanthanide(III)-doped Y4(SiS4)3"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-05-15T10:28:58.363964+00:00"}
