Studies of photon induced electron excitation and transfer

Studies of photon induced electron excitation and transfer: sensors, solar cells, and photodynamic therapy

Three projects are related to this topic. One is to study the mechanism of electron excitation and tranfer upon absorption of photons in fluorescence sensors. The second project is to study the mechanism of electron excitation/transfer in organic dyes used in solar cells, and the third is to study the mechanism and kinetics of generating long-lived triplet states for photodynamic therapy photosensitizers.
