Electronic and Photonic Materials Physical Chemistry

ur research focuses on deeper understanding of chromophore-metal interactions resolving observables in energy, space and time domains using apertureless near-field scanning optical microscopy and spectroscopy. Our near-field optical microscope achieves spatial resolution in the order of 10 nm, and we aim to exploit this unique capability of optical resolution to investigate energy and charge transfer that inherently takes place when the donor and acceptor materials are in close proximity (less than 30 nm separation). The research projects in our group includes

Energy transfer in coupled quantum dot and plasmonic nanostructures DNA mediated optical coupling Semiconductor-metal hybrid nanomaterials Fabrication and optical characterization of plasmonic sensors and probes
