Photoluminescence microscopy is used to identify individual nanotubes and to determine their lengths and chiral indices. Exciton diffusion length is obtained by comparing the dependence of photoluminescence intensity on the nanotube length to numerical solutions of diffusion equations. We find that the diffusion length in these clean, as-grown nanotubes is significantly longer than those reported for micelle-encapsulated nanotubes.", "subitem_description_type": "Abstract"}]}, "item_2_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society"}]}, "item_2_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1103/PhysRevLett.104.247402", "subitem_relation_type_select": "DOI"}}]}, "item_2_relation_26": {"attribute_name": "\u7570\u7248\u3067\u3042\u308b", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://dx.doi.org/10.1103/PhysRevLett.104.247402", "subitem_relation_type_select": "URI"}}]}, "item_2_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "Copyright (C) 2010 The American Physical Society."}]}, "item_2_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Journal Article"}]}, "item_2_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "Institute of Engineering Innovation, The University of Tokyo"}, {"subitem_text_value": "Global Edge Institute, Tokyo Institute of Technology"}, {"subitem_text_value": "Department of Mechanical Engineering, The University of Tokyo"}, {"subitem_text_value": "PRESTO, Japan Science and Technology Agency"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Moritsubo, S."}], "nameIdentifiers": [{"nameIdentifier": "3687", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Murai, T."}], "nameIdentifiers": [{"nameIdentifier": "3688", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shimada, T."}], "nameIdentifiers": [{"nameIdentifier": "3689", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Murakami, Y."}], "nameIdentifiers": [{"nameIdentifier": "3690", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Chiashi, S."}], "nameIdentifiers": [{"nameIdentifier": "3691", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Maruyama, S."}], "nameIdentifiers": [{"nameIdentifier": "3692", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kato, Y.
