Research Interests

Current research interests are focused on the high energy excited states of ions in solids, especially rare earth ions. The main objective is the development of new phosphors with improved efficiency which can be applied in mercury-free fluorescent lamps and in plasma displays. These phosphors are excited in the vacuum ultraviolet and emit two (or more) photons for each input photon and are referred to as quantum cutting phosphors. In addition, research activity continues on the optical dynamical properties of rare earth-doped nanoparticles.
