About Uday 

Udayabhaskararao Thumu joined INL in 2017 and he is currently working as a Research Fellow through Marie Curie action (NanoTRAINforGrowth II) and studying the optical properties of nanodevices based on colloidal semiconductor and perovskite nanocrystals for photovoltaic applications.

Prior to joining INL, in Braga, his postdoctoral research focused on the thermodynamic control of phase transformations and photophysics of perovskite nanocrystals at Department of Physics of Complex System, Weizmann Institute of science, Israel. His first postdoctoral research was conducted at the Department of Organic Chemistry, Weizmann Institute of Science on the self-assembly of binary nanocrystals and the post modifications for bottom-up nanofabrication. He also experienced in noble metal nanocluster research, synthesis & characterisations and their catalytic, sensing applications during his doctoral research at Indian Institute of technology Madras, India. Prior to joining Ph.D, he completed his Master’s degree in Chemistry from Andhra University, Vishakhapatnam, India.

 

 

The Cofund project

Creation of new materials always fascinates researchers as it provides immense opportunities to scientific understanding and technological advancement. In this project, we aim to fabricate and investigate novel hybrid nanomaterials. Hybrid materials, consisting of two components having significantly different physical properties, often exhibit emergent properties which are absent in either one of the separate components. Colloidal semiconductor quantum dots (QDs) and cesium lead halide perovskite nanocrystals (CsPbX3 NCs, X = Cl, Br, I)) are two classes of novel materials. Semiconductor QDs have been intensively studied in the last few years in various contexts, ranging from fundamental optical properties to device engineering. On the other hand, CsPbX3 NCs are the newest addition to the family of organic‒inorganic perovskite materials. My research involves the development ofmethodologies to couple QD and perovskite interfaces and unifying them as one material and study their interesting optical properties. This research aims to reduce non-radiative recombination processes in nanocrystal solids to enhance charge-carrier separation and potential applications in solar light harvesting.
