The Chemistry Programme, under the School of Indigenous Knowledge Science and Technology (SIKST) and the Centre for Indigenous Innovation and Entrepreneurship, KISS-DU organized a Distinguished Invited Lecture on How to make stable Perovskite Nanocrystals: For LED and Photocatalytic applications on 21st April 2023. Dr. Nimai Mishra, Associate Professor, Department of Chemistry, Institute of Chemical Technology Mumbai- Indian Oil Corporation (ICT-IOC), Odisha Campus was invited as the speaker on the occasion. This was organized under the aegis of Institutional Innovation Council, Ministry of Education, Govt. of India.
In the Welcome Address Dr. Snigdharani Panda Chairman Council of Deans, KISS-DU talked about the importance of observing the world creativity and innovation day and pondered on the various possibilities of involving the students of KISS in the innovation of new things. The distinguished invited speaker Dr. Nimai Mishra, was introduced by Dr. Tanushree Das, Assistant Professor, Chemistry Programme, as an eminent scientist and academician with excellent publications and citations.
Dr. Mishra delivered presentation on how to make stable Perovskite Nanocrystals: For LED and Photocatalytic applications. In his presentation he explained about the fundamentals of synthesis and challenges of Perovskite nanocrystals and their applications as light-emitting diodes (LEDs) and other significant applications in photovoltaics and optoelectronics. He discussed a facile and efficient completely amine-free synthesis of cesium lead bromide perovskite nanocrystals using a novel bromide source and n-trioctylphosphine (TOP) as a ligand in open atmospheric conditions. These amine-free CsPbBr3 NCs films exhibiting high photoluminescence (PL) at open atmospheric conditions, which can be further used for optoelectronic device applications. Further, he also shared the results of the photostability of these nanocrystals with respect to various capping ligands for surface passivation to obtain high photostability and good in NCs dispersions and focused on the impact of CsPbBr3 nanocrystal surface modification for efficient photocatalytic application.
Speaking on the occasion Dr. Bikram Keshari Das, Head of Chemistry Programme, KISS-DU proposed options for a possible collaboration with KISS-DU and ICT-IOC for research and academic activities.
The session concluded with an active round of discussion and a formal Vote of Thanks by Dr. Yasobanta Das, Dean, School of IKST, KISS-DU.
