OSA Fellow Lecture: Excited State Dynamics of Nanomaterials for Light Harvesting

2 June 2021, 9:00 - 10:00 - Chennai, Kolkata, Mumbai, New Delhi (UTC + 05:30)

Nanomaterials-based light harvesting systems have been the subject of research because they are able to generate exciton after photoexcitation. This webinar focuses on understanding light harvesting processes like exciton dynamics, energy transfer, antenna effect, charge carrier dynamics, and other related processes of semiconducting quantum dots (QDs), -conjugated semiconductor nanoparticles, hybrid nanostructures, and porphyrin based nanostructures. Ultrafast spectroscopic investigations provide direct insight into the impacts of electron and hole transfer at the interface in the hybrid materials for photocatalysis and photocurrent generation to construct efficient light harvesting systems. The fundamental knowledge of these photophysical processes is crucial for the development of efficient light harvesting systems.
