Recently, LIBS has been used to evaluate the hardness of a material. This approach capitalizes on the findings that harder surface produce faster laser-induced plasma shockwave, eventually giving rise to higher density plasmas. This promotes excitation and ionization of neutral atoms. Thus, the ratio of the ionic to neutral emission intensity and the electron temperature from LIBS measurements allows us to evaluate the surface hardness. In the present study, we assess the potential use of emission lines from ambient gas instead of that from investigated elements to diagnose surface hardness using a portable fiber-optic LIBS device.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"11th International Conference on Laser-Induced Breakdown Spectroscopy (LIBS2020)","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nakanishi, Ryuzo"}],"nameIdentifiers":[{"nameIdentifier":"889276","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oba, Hironori"}],"nameIdentifiers":[{"nameIdentifier":"889277","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakanishi, Ryuzo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"889278","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oba, Hironori","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"889279","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Fiber-optic LIBS for evaluation of surface hardness using ambient gas emission","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fiber-optic LIBS for evaluation of surface hardness using ambient gas emission"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-09-07"},"publish_date":"2020-09-07","publish_status":"0","recid":"80550","relation_version_is_last":true,"title":["Fiber-optic LIBS for evaluation of surface hardness using ambient gas emission"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:31:09.082716+00:00"}
