Under strong excitation, the TA dynamics in CIS QDs is well described by a simple rate equation including single-carrier trapping, free-to-bound recombination, and trap-assisted Auger recombination. Under weak excitation, on the other hand, the PL decays of the QDs are composed of a short-lived component caused by surface trapping and a long-lived one caused by free-to-bound recombination. It is found that the surface trapping accelerates markedly with decreasing QD size while the free-to-bound radiative recombination hardly depends on the QD size. Besides this, we observed both a decrease in the PL lifetimes and a dynamic spectral redshift, which are attributed to the surface trapping and the coexistent inhomogeneous broadening in CIS QDs. The spectral redshift becomes less pronounced in CIS/ZnS core/shell QDs because of the suppression of the fast nonradiative recombination caused by the passivation of the surface traps. These results give clear evidence that the free-to-bound model is appropriate for interpreting the optical properties of CIS QDs.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Royal Society of Chemistry"}]},"item_5_relation_10":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"25728207","subitem_relation_type_select":"PMID"}}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1039/C5CP00034C","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"©the Owner Societies 2015"}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1463-9076","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11301773","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sun, Jianhui"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ikezawa, Michio"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Wang, Xiuying"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Jing, Pengtao"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Li, Haibo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Zhao, Jialong"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Masumoto, Yasuaki"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-03-01"}],"displaytype":"detail","filename":"PCCP_17-18.pdf","filesize":[{"value":"893.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PCCP_17-18","url":"https://tsukuba.repo.nii.ac.jp/record/36114/files/PCCP_17-18.pdf"},"version_id":"1f8af15d-c462-4200-8e0f-7b3aba2bb522"}]},"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":"Photocarrier recombination dynamics in ternary chalcogenide CuInS2 quantum dots","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Photocarrier recombination dynamics in ternary chalcogenide CuInS2 quantum dots"}]},"item_type_id":"5","owner":"1","path":["491","134","3128"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-11-25"},"publish_date":"2015-11-25","publish_status":"0","recid":"36114","relation_version_is_last":true,"title":["Photocarrier recombination dynamics in ternary chalcogenide CuInS2 quantum dots"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:05:07.427241+00:00"}
