Yet, knowledge regarding the formation mechanism in very small particles is still limited. Here, the study was focused on the formation of the smallest NV--containing diamonds, 5 nm detonation nanodiamonds (DNDs). As a reliable method to quantify NV- centers in nanodiamonds, half-field signals in electron paramagnetic resonance (EPR) spectroscopy are recorded. By comparing the NV- concentration in a series of nanodiamonds (5 - 100 nm), it was shown that the formation process in DNDs is unique in several aspects. NV- centers in DNDs are already formed during electron irradiation, without the need for high-temperature annealing. The effect was interpreted in terms of “self-annealing”, where size and type dependent effects enable vacancy migration at lower temperature. Although NV- concentration increases with particle size, the NV- concentration in NDs surpasses that of 20 nm-sized nanodiamonds. Using Monte-Carlo simulations, we show that the higher substitutional Nitrogen concentration compensates the vacancy loss induced by the large particle surface. Upon 1.5 × 1019 e-/cm2 electron irradiation, DNDs show a 12.5-fold NV- increment with no sign of saturation. These findings can be of interest for the creation of defects in other very small semiconductor nanoparticles.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Chemical Society Publications"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1021/acs.jpcc.1c10466","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1021/acs.jpcc.1c10466","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1932-7447","subitem_source_identifier_type":"ISSN"}]},"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":" So, Frederick"}],"nameIdentifiers":[{"nameIdentifier":"1043097","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"I.
