Synthesis and properties of metal oxide, semiconductor and hybrid organic-inorganic nanomaterials
The wide band gap TiO2 has properties such as higher exciton binding energy, good electrical conductivity and high transparency in the visible light region which makes it preferable material for applications in optoelectronic devices. These devices require synthesis of good quality TiO2 thin films and nanocrystals. It is well known that p-n junction or diode is the basic building block for any electronic device. It is also known that the undoped TiO2 has a good intrinsic n-type conductivity which can be further improved by doping. The efficient p-type doping of TiO2 has yet to be achieved.
The nanocrystals have higher scope of functionalization due to the higher surface-to-volume ratio and three dimensional quantum confinements of electrons and excitons. The functionalization of TiO2 nanocrystals may be achieved by making its hybrid nanocomposite with an organic material. Inorganic-organic hybrid nanocomposites integrate the useful inorganic and organic characteristics within a single composite. These nanocomposites are expected to exhibit unique electronic and optical properties. In view of the foregoing, the aim of my research is to understand the basic science of the synthesis, characterization and sensitization of various morphologies of TiO2 with CdSe quantum dots and poly[2-methoxy-5-(2’-ethylhexyloxy)-p-phenylene vinylene] (MEHPPV). 

Another aspect of my research is to create awareness about the intellectual property rights among the teachers and students. In this era of start ups it indeed holds a great potential in terms of career opportunities.
