This study demonstrates the first experimental evidence of the directional variation of thermal emission from nonspherical particles of a size smaller than the geometric optics limit. We used a method of laser-induced incandescence with multi-angle detectors to observe the directional dependences of thermal emission from individual carbon particles. For laboratory carbon particles with various shapes, the measured directional dependences of thermal emission were consistent with theoretical calculations for model nonspherical particles. This study provides a new physical principle for measuring the shape of aerosols according to the directional dependence of their thermal emission and is especially useful for online, in situ shape classification of carbon particles."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670318698361859","@type":"Researcher","foaf:name":[{"@value":"Nobuhiro Moteki"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670318698361857","@type":"Researcher","foaf:name":[{"@value":"Yutaka Kondo"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670318698361856","@type":"Researcher","foaf:name":[{"@value":"Nobuyuki Takegawa"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670318698361858","@type":"Researcher","foaf:name":[{"@value":"Shin-ichi Nakamura"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00218502"}],"prism:publicationName":[{"@value":"Journal of Aerosol Science"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"2009-09","prism:volume":"40","prism:number":"9","prism:startingPage":"790","prism:endingPage":"801"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/","https://www.elsevier.com/legal/tdmrep-license"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:S0021850209000937?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:S0021850209000937?httpAccept=text/plain"}],"createdAt":"2009-05-21","modifiedAt":"2025-09-17","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360002217244831360","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Consistency and Traceability of Black Carbon Measurements Made by Laser-Induced Incandescence, Thermal-Optical Transmittance, and Filter-Based Photo-Absorption Techniques"}]},{"@id":"https://cir.nii.ac.jp/crid/1360005517068507136","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Capabilities and limitations of the single-particle extinction and scattering method for estimating the complex refractive index and size-distribution of spherical and non-spherical submicron particles"}]},{"@id":"https://cir.nii.ac.jp/crid/1360016864718960000","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Identification and particle sizing of submicron mineral dust by using complex forward-scattering amplitude data"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285707208860032","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Analysis of the mixing state of airborne particles using a tandem combination of laser-induced fluorescence and incandescence techniques"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567184078218752","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Multiangle Polarimetry of Thermal Emission and Light Scattering by Individual Particles in Airflow"}]},{"@id":"https://cir.nii.ac.jp/crid/2050307417136237056","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Climate-relevant properties of black carbon aerosols revealed by in situ measurements : a review"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1016/j.jaerosci.2009.05.003"},{"@type":"OPENAIRE","@value":"doi_dedup___::ce8d47dd599f4c5d50995797d88b8038"},{"@type":"CROSSREF","@value":"10.1080/02786826.2010.533215_references_DOI_HogJKXZLiBKwUQGSaXGZIc8GWn0"},{"@type":"CROSSREF","@value":"10.1080/02786826.2022.2057839_references_DOI_HogJKXZLiBKwUQGSaXGZIc8GWn0"},{"@type":"CROSSREF","@value":"10.1080/02786826.2011.583299_references_DOI_HogJKXZLiBKwUQGSaXGZIc8GWn0"},{"@type":"CROSSREF","@value":"10.1186/s40645-023-00544-4_references_DOI_HogJKXZLiBKwUQGSaXGZIc8GWn0"},{"@type":"CROSSREF","@value":"10.1016/j.jqsrt.2019.106811_references_DOI_HogJKXZLiBKwUQGSaXGZIc8GWn0"},{"@type":"CROSSREF","@value":"10.1016/j.jaerosci.2015.05.002_references_DOI_HogJKXZLiBKwUQGSaXGZIc8GWn0"}]}
