Autorenporträt

Professor Ana de Bettencourt-Dias, University of Nevada, Inorganic and Materials Chemistry Professor de Bettencourt-Dias' research interests lie in the development of new ligands (particularly organic and transition metal complexes) for highly emissive lanthanide ion complexes. She first became active in the field of the luminescent lanthanide ions in 2001 when she took her first academic position at Sycrause University, and her publications in this area include two well-received review articles which have been cited over 80 times. Professor de Bettencourt-Dias co-organised a symposium on 'Luminescence and Magnetism of Lanthanide-Containing Materials' at the ACS 2010 Fall Meeting, and she is program chair for the 2011 Rare Earth Research Conference. In addition to her research, Professor de Bettencourt-Dias currently teaches classes in Advanced Inorganic Chemistry and Chemistry of the Less Common Elements.
