Optical spectroscopy of lanthanide’s ions doped in laser active materials, nanocrystals, micro/mesoporous materials and organic-inorganic systems.

Issues of interest: host-guest interactions in terms of the electronic structure, clustering effects, excited states dynamics and excitation energy transfer processes.

Techniques and methods: high resolution laser excited total luminescence, excitation, fluorescence lifetime measurements, laser induced fluorescence line narrowing, time resolved site selection spectroscopy.
