Duarte Ananias is an auxiliary researcher at CICECO, Aveiro Institute of Materials, at the University of Aveiro. Since his PhD degree, December 2004, he has developed research on lanthanide containing materials, as postdoc granter and assistant researcher. From 2005 to 2007 he received a first FCT postdoctoral grant to study new luminescent microporous lanthanide silicates and to explore their application as contrast agents for magnetic resonance imaging, under the supervision of João Rocha and Luís D. Carlos (University of Aveiro), and Carlos Geraldes (University of Coimbra). Next, from January 2008 to May 2009, under the supervision of João Rocha (University of Aveiro) and Kajsa Uvdal (University of Linkoping; Sweden) he started his research on the field of lanthanide oxide nanoparticles. During the postdoc program he moved to Linkoping (Sweden) from April 2008 to June 2008. Under the FCT Ciência 2008 program, he was an assistant researcher at CICECO (University of Aveiro) from June 2009 to May 2014. In this context he continued the research on lanthanide silicates and on lanthanide oxide nanoparticles, but also developed considerable collaborations on the photoluminescence study of other lanthanide based materials such as metal-organic frameworks and polyoxometalates. He also collaborates on the teaching activities of the University of Aveiro as a volunteer (2/4 hours per week of practical classes on Elements of Physical Chemistry and General Chemistry, respectively, for the first and second semester). From May 2014 to August 2020 D. Ananias was a postdoc researcher (FCT grant) at CICECO under the supervision of João Rocha and Luís D. Carlos continuing to develop research on luminescent materials. His main research interest is the study of lanthanide luminescence properties of microporous and layered lanthanide silicates, metal-organic frameworks, and lanthanide containing nanoparticles. He published 3 book chapter, and 78 papers in international peer review journals, with an accumulated impact factor (2023) higher than 500, over 5200 citations and an h-index of 31 (Scopus). 21 of the papers were published in journals with 2023 impact factor higher than 9 in the multidisciplinary areas of Chemistry and Materials Sciences: 7 J. Am. Chem. Soc., 4 Chem. Mater., 3 Adv. Funct. Mater., 3 Angew. Chem. Int. Ed., 2 Adv. Mater. and 1 Chem. Soc. Rev. and 1 Chem. Sci..
