Title: Light-Harvesting Systems Based on Semiconductor Nanocrystals
Abstract: The integration of semiconductor nanocrystals with photo- and redox-active organic molecules
has emerged as a promising strategy to harvest visible-light and use them in several applications,
such as photovoltaics, light-emitting devices, and sensing. A comprehensive understanding of
photoinduced processes such as exciton dynamics, charge transfer, and energy transfer is essential
for the continued development of these technologies. This talk will highlight the development in nanohybrid materials based on metal halide perovskite nanocrystals, with a focus on representative examples with application in photocatalysis. Furthermore, recent results on carbon-based nanomaterials will be presented.
Dr. Raquel E. Galian obtained her Ph. D. in Chemistry Science at the Universidad Nacional de Cordoba, Argentina (2001). She did postdoctoral stays at Polytechnic University of Valencia, University of Valencia and University of Ottawa, Canada. During those periods she has done several contributions in photosensitized process induced by aromatic ketones and the functionalization of photonic crystal fibers with quantum dots. In 2007, she was awarded with the prestigious Ramon y Cajal contract at the University of Valencia obtained a permanent position as Scientist Research in 2017 and now is Associate
Professor in the Department of Organic Chemistry at the same University. Her research line is focused in the “synthesis and functionalization of photoactive semiconductor nanocrystals and novel nanoarchitecture for photocatalysis, and as emissive materials”. She has authored more than 85 scientific publications and delivered over 180 contributions at National and International Conferences. Moreover, has given several Invited lectures at the City University of Hong Kong (Hong Kong), Universidad Nacional de Córdoba, Buenos Aires y Santiago del Estero (Argentina), Università degli Studi della Basilicata (Italy), University of Wuppertal and University Ludwig-Maximilians-Universität München (Germany) and Tampere
University (Finland).
