My research focuses on the synthesis of nanocrystals for the study of fundamental science and economic applications. The interest in nanocrystals stems from the fact that these materials show properties dependent on the size of the crystals. Hetero-nanostructures and hybrid materials provide an alternative opportunity to engineer the required nanocrystals properties, not by tailoring the size but their composition and hence suggest themselves to be an important group of semiconducting materials for further advancements in the field of photocatalysis, LED, photovoltaic and sensor technology. I am actively involved in researching and developing new materials exhibiting bright luminescence and light harvesting; the ultimate aim being applications in photocatalysis, LEDs, photovoltaics, biological labeling and sensor technology applications. I am also working on developing non-toxic materials as an alternative to cadmium chalcogenides.
