I have worked in the design and development of novel donor-acceptor systems for efficient light harvesting studies. My PhD research focuses on controlling the interparticle forces at the nanoscale to realize improved photophysical processes from the existing nanomaterials, especially with quantum dots (QDs). The processes consist of Förster resonance energy transfer (FRET), photoinduced electron transfer (PET), dexter energy transfer (DET) and so on. We believe that fine-tuning of surface interaction not only controls the external forces but also commands the internal interactions such as electronic coupling or band level resonance which help in achieving an efficient light harvesting. Working with water dispersed nanomaterials permits in regulating some of the essential forces such as electrostatics, H-bonding, hydrophobic interaction and so on. As a researcher, I have expertise in synthesizing a variety of nanomaterials of different size and shapes, surface modifications, characterization of nanomaterials, analysing spectroscopic and microscopic observations and photophysical investigations. The exploration of interaction driven photophysical processes will help in excavating the true potential of large surface area of nanomaterials and their easy accessibilities towards the development of better optoelectronic devices, sensors and so on.
