About Us

The Nano Spectroscopy(NaSpec)group is a team of highly motivated and enthusiastic professors, researchers and students. The primary research interest of this team is to utilize spectroscopic and related techniques to study various physical phenomena at the nanoscale. Apart from studying the basic properties of materials at nanoscales, one of the interesting applications is to achieve a nanometric spatial resolution in optical imaging. This is done by combining plasmonics and near-field effects to Raman and photoluminescence spectroscopies, which allows one to "see" nanomaterials through visible light. We are also interested in innovatively manipulating light of various wavelengths and to confine it within nanometric volumes for some very interesting applications at the nanoscale.
