Research Interests

Colloidal semiconductor (quantum dots) and metal nanocrystals.

Using the colloidal chemistry approaches we synthesize semiconductor and metal nanorystals of variable sizes, shapes and compositions, tuning the emission of semiconductor nanocrystals and surface plasmon resonances of metal nanoparticles through the visible and near-IR spectral range.

Colloidal nanocrystals, with their variable surface chemistry determined by a rich choice of capping ligands are ideal building blocks for fabrication of different hybrid nanostructures. We apply optical spectroscopy to study energy transfer and charge separation in these nanostructures and look for different applications of semiconductor and metal nanocrystals such as light-emitting devices and photodetectors.
