Fluorescence Resonance Energy Transfer of Complex Molecular System

The organic compounds that emit at different wavelength regions have been selected to study. Fluorescent dyes play an important role for staining and sensoring in analytical chemistry, environmental science, biology and medicine. Some fluorescent dyes are laser active and are used in dye lasers. In recent years the research interests changed from liquid dye lasers to solid state dye lasers.Often organic polymers are used as solid matrices for organic dyes. Semiconducting (conjugated) polymers have properties that make them attractive as the gain material for solid state lasers. Dye lasers utilizing a solid host are very attractive for a wide range of applications. For example, in medicine can use in cardiology for ablation of blood clots, photodynamic therapy for photo-radiation and bio-stimulation, biological field DNA detection and sequencing, remote sensing of atmospheric contaminants, underwater communications, holography, optoelectronic applications.
