A Possibility of Functional Devices Based onPolysilane/Organic Dye-Mixed Films

It is attractive to realize symbiotic optical devices by silicon-based one-dimensional polymers, i.e. polysilanes, since they have relatively high mobility of holes and high excitonic oscillator strength for light emission. We fabricated visible (Red, Green, Blue and White) electroluminescence device by utilizing resonant energy transfer from a polysilane to energy-matched organic dye molecules. These pairs can be used as photo-detectors. We have shown also that the combination ofthe polysilane and dye molecules is effective for a wavelength-selectable photoconductor by observing 520nm light irradiation
