Welcome! The research of our group is focused on nano/microstructured luminescent materials for advanced biological and photonic applications. In particular, we use lanthanide and transition metal ions as dopants to modify optical properties of insulator and semiconductor host materials. We exploit the dopant-dopant interaction as well as dopant-host interaction for designing different optical processes to meet specific needs in practical applications.
