All the alloys were annealed at 850 °C and mirror-polished to observe their reflectance curves in the visible spectrum and three-dimensional color coordinates. All the alloys were composed of a major phase of Ag-Au-rich matrix and a minor and almost colorless Pt-Cu-rich phase. It was found that the color of the alloys was substantially controlled by the Ag-Au-rich matrix and that with increasing Au/Ag atomic ratio from 0.130 to 0.996, the yellow-blue chromaticity index b * increased from 8.0 to 14.4, giving a pale yellow color. This systematic increase in yellowness was caused by a continuous shift of the absorption edge of reflectance curve toward longer wavelengths with increasing Au/Ag atomic ratio.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Journal of Materials Science, 44(11), pp.2796-2804; 2009","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Netherlands"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s10853-009-3368-0","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c Springer Science+Business Media, LLC 2009"},{"subitem_rights":"The original publication is available at www.springerlink.com"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00701725","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00222461","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"1573-4803","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"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":"Shiraishi, Takanobu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takuma, Yasuko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujita, Takeshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miura, Eri"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hisatsune, Kunihiro"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"JMS44_2796.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JMS44_2796.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/16614/files/JMS44_2796.pdf"},"version_id":"4ab4c6ef-7fa5-4149-bf55-133f48d6df62"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Dental alloy","subitem_subject_scheme":"Other"},{"subitem_subject":"Gold alloy","subitem_subject_scheme":"Other"},{"subitem_subject":"Color","subitem_subject_scheme":"Other"},{"subitem_subject":"Optical property","subitem_subject_scheme":"Other"},{"subitem_subject":"Reflectance","subitem_subject_scheme":"Other"},{"subitem_subject":"Spectrophotometric colorimetry","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":"Optical properties and microstructures of Pd-free Ag?Au?Pt?Cu dental alloys","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Optical properties and microstructures of Pd-free Ag?Au?Pt?Cu dental alloys"}]},"item_type_id":"2","owner":"2","path":["11"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-11-20"},"publish_date":"2009-11-20","publish_status":"0","recid":"16614","relation_version_is_last":true,"title":["Optical properties and microstructures of Pd-free Ag?Au?Pt?Cu dental alloys"],"weko_creator_id":"2","weko_shared_id":2},"updated":"2023-05-15T19:02:11.364072+00:00"}
