Fernando B. Dias Department of Physics University of Durham Biography Publications Institution JoVE Articles Fernando B. Dias Fernando B. Dias is an Associated Professor in Material Physics at Durham University. Dias has extensive experience on the investigation of molecular photophysics, and in particular on compounds designed for application in light emitting diodes and solar cells.Dias’ current research is centred on the investigation of the excited state dynamics of molecular emitters, aiming to investigate mechanisms that underpin the observation of thermal activated delayed fluorescence in small molecules and polymers, room temperature phosphorescence in metal-free emitters, and efficient NIR emission in organic emitters and metal complexes. Dias combines spectroscopy methods with detailed kinetic analysis and device fabrication to investigate the interplay between the energy ordering of electronic excited states and structure-property relationships, aiming to maximize the performance of molecular materials in relevant technological areas.
