L.Santamaría, JesúsNitrogen-doped luminescent carbon nanodots for optimal photo-generation of hydroxyl radicals and visible-light expanded photo-catalysisART-2016-94711Luminescent carbon nanodots (CNDs) have been obtained by hydrothermal processing of ascorbic acid (AA) and ethanolamine (EN). The resulting N-doped carbon nanostructures exhibit interesting and tunable emission capabilities with a dual behavior as down-converters and more importantly, as up-converting quantum dots. Herein, we also evaluate the optical response of these CNDs to selectively generate highly reactive oxidative hydroxyls (OH) upon irradiation with different light-emitting diodes (LEDs) in the visible-NIR range. Finally, the role of the N-doped CNDs as nano-sensitizers to maximize the solar light harvesting and expand the photo-catalytic response of a commonly used UV-active catalyst such as TiO2 was successfully tested in the degradation of an organo-chlorinated compound under visible light.2016http://zaguan.unizar.es/record/15111210.1016/j.diamond.2016.03.021http://zaguan.unizar.es/record/151112oai:zaguan.unizar.es:151112info:eu-repo/grantAgreement/EUR/ERC/HECTOR-267626info:eu-repo/grantAgreement/EC/FP7/294094/EU/Synthesis and characterization of NANOstructured materials with LumInescent properties for diaGnostic and tHerapeuTic applications/NANOLIGHTDiamond and Related Materials 65 (2016), 176-182by-nc-ndhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.esinfo:eu-repo/semantics/closedAccess
