A visible-light sensitized Er3+complex based on the use of a highly conjugated ß-diketonate (1, 3-di(2-naphthyl)-1, 3-propanedione, Hdnm) and 5-nitro-1, 10-phenanthroline (5NO2phen) as an ancillary ligand, [Er(dnm)3(5NO2phen)], has been synthesized, fully characterized and its photophysical properties have been investigated. Suitably expanded p-conjugation in the complex molecule makes the excitation window red-shifted to the visible region (up to 550 nm). Efficient energy transfer by antenna effect results in 1.53 µm emission from the Er3+ion.2015http://zaguan.unizar.es/record/7022310.1016/j.jallcom.2014.09.090http://zaguan.unizar.es/record/70223oai:zaguan.unizar.es:70223info:eu-repo/grantAgreement/ES/MINECO/MAT2013-46649-C4-4-Pinfo:eu-repo/grantAgreement/ES/MINECO/MAT2010-21270-C04-02info:eu-repo/grantAgreement/EC/FP7/303535/EU/Chromophore-Sensitized Up-Conversion in Lanthanide Materials/CHROMSENSUCinfo:eu-repo/grantAgreement/ES/FEDER/CSD2007-00045JOURNAL OF ALLOYS AND COMPOUNDS 619 (2015), 553-559by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
