Supervisor: Dr. Christopher Milne, Dr. Dmitry Khakhulin, Prof. Dr. Dorota Koziej * Investigating polynuclear transition metal complexes using optical and ultrafast X-ray spectroscopies for energy conversion, photocatalysis, chemical sensing, and bio-imaging. * Studying the structural and electronic origins of enhanced efficiency of charge transfer, metallophilic interactions, and their cooperativity in transient electronically excited states. * Analysing the effect of solvation shells in different solution

Supervisor: Prof. J. Feldmann Chair for Photonics and optoelectronics * Developed a new synthetic procedure of Mn2+ doped CsPbCl3 Perovskite nanocrystals (NCs) with increased photoluminescence quantum yield (PLQY) from 23% to 30%. * Investigated the formation of Ruddlesden–Popper defects within host perovskite NCs which was first identified in these crystal structures. * Such doping of Mn in the perovskite nanocrystals demonstrates manganese-doping-induced quantum confinement. * Depending on the concentrat

Supervisor: Prof. Dr. Jochen Feldmann Chair for Photonics and Optoelectronics * Produced Pb-free metal halide perovskite nanocrystals (CsPbBr3 and CsPbCl3) with tunable photoluminescence using innovative one-pot ultra-sonication method. * Explored the optical and optoelectronic properties of nanocrystals and achieved chemical cutting of nanowires into nanorods. * Investigated the surface passivation of ligands and inorganic salts affecting the photoluminescence quantum yield of lead halide nanocrystals.

Supervisor: Prof. Dr. Akhilesh Kumar Singh School of Basic Science * Designed, synthesized, and characterized macrocyclic and macro-acyclic organic ligands. * Successfully converted the ligands to the coordination compounds with 3d, 4f, and 3d-4f mixed metal ions. * Conducted crystallographic studies to examine the structural diversity of complexes in grid-like and triangular-like complexes. * Investigated the effect of host-guest interaction in the compounds. * Investigated magnetic properties, fluorescen

Supervisor: Prof. Dr. Himansu Sekhar Biswal School of Chemical Sciences * Designed and synthesized a macro ligand with a large number of N and O as binding sites. * Prepared a biochemically important Co(III) complex with the ligand and H2O molecule. * These Co complexes are biologically important for human beings. * Explored nuclearity, supramolecular structure, and the kinetics of ligand exchange in the complex. Thesis submitted: “Synthesis and study of the kinetics of Ligand Exchange (water) in Cobalt

The stimuli-responsive metal dimers are synthesized by me in collaboration with chemistry department which will be studied in the X-ray beam at different beam line including European XFEL GmbH, Petra III at DESY Synchrotron and ESRF at Grenoble.

Completed Master's in Chemistry where the specialisation was in Inorganic Chemistry.
