Research Division Dr. Beatriz Julián

Nanoparticles and nanohybrids

The main interest of the division is the development of new luminescent inorganic and hybrid organic–inorganic materials, textured at different scales, for their application in photonics, energy, ceramics and catalysis. We focus on the synthesis, characterization and evaluation of nanostructures (from nanoparticles to micrometric powders) containing lanthanide ions due to their unique optical processes (fluorescence, phosphorescence, non-linear processes, up- and down-conversion…). By combining self-assembly and Soft-Chemistry processes as well as conformation techniques (films, monoliths, fibers…), a huge range of materials with tailored structure (morphology, size, crystalline phase) and properties can be envisaged. Especially relevant for our research is to understand the mechanisms for the formation of the structure in order to provide materials with enhanced properties for specific technological applications. Our current efforts focus on nanostructures with up-conversion properties able to absorb near-IR radiation and convert it into UV and VIS light for luminescent solar concentrators, solar-fuels and photocatalysis. Our division also addresses the study of the photophysical properties and their dependence with the composition and nanostructure of the materials, including inorganic crystals and also hybrid organic-inorganic composites.

Short biography of Dr. Julián

Dr Beatriz Julián-López was born in 1977. She obtained her B.Sc. degree in chemistry (1995–1999) at the Jaume I University of Castellón (Spain), where she also received her Ph.D. in Chemistry of Materials (1999–2003). Her first work was focused on the synthesis of ceramic pigments by nonconventional methods, but during her Ph.D. she specialized in the synthesis and characterization of sol–gel hybrid organic–inorganic materials for optical applications. In 2004 she moved to Paris for a post-doctoral formation at Prof. C. Sanchez’s Laboratory (University of Pierre and Marie Curie), addressed to get expertise on the synthesis of mesoporous and nanostructured materials. In 2007 she came back to Jaume I University with a “Ramon y Cajal” research contract, where she is nowadays Associate Professor (2011). Since 2012 she leaders the Group of Multifunctional Materials (GMM) towards the development of novel multifunctional inorganic and hybrid organic–inorganic materials, textured at different scales, for optical, energy, ceramics and biomedical applications. With h-index 19, she published 50 papers in research journals with more than 2500 citations.
