| Abstract(in English) | Polysilanes have high excitonic emission efficiency in UV region as well as one-dimensional conductivity. We realized the first polysilane-based electroluminescence in wide visible-wavelength range by utilizing an efficient resonant-energy transfer to energy-matched organic dye molecules in their spin-coated mixed films. The method has a fundamental advantage of controlling blue (B), green (G) and red (R) components in the spectrum simply by mixing dye molecules in solution. In practice, however, detailed consideration on the energy transfer among dye molecules was necessary in the previous combination. Here we propose another combination of TPB, coumarin 6 and Eu complex for an energy donor of polymethylphenylsilane (PMPS). An independent control of B and R became possible owing to no overlap in energy between TPB and Eu complex. The energy of G emission comes from the energy transfer from TPB, but high solubility of TPB makes it possible to control G/B ratio easily also. The combination, therefore, improved the controllability of the EL spectrum and the purity of white emission based on PMPS. |
