| Research Abstract |
The white light-emitting organic EL device which combined the blue and red emission layers was produced, and optimization of the device structure by optical design considered the improvement of luminous efficiency. For this reason, the multi-scale optical analysis technique which integrated wave optics, an electromagnetic theory of light, and near-field optics was developed, and conversion to reduction of a surface plasmon loss and the external emission mode of thin film waveguide mode was considered. As a result, we can obtained 195 lm/W in power efficiency, 47% in external quantum efficiency, and light extraction efficiency not less than 50% of efficient organic EL device..
