| Research Abstract |
We have newly developed white-light-emitting organic devices by employing side-coupling color conversion method, in which the lateral emission originating from the emitting layer is propagated to adjacent color conversion layers. In addition, optical analysis of the device performance was done by using original software on the basis of Fresnel's theory in order to clarify optical mode distribution in the device. The white light emitting device showed power efficiency of 39-lm/W and external quantum efficiency of 19% with color coordinates (0.29, 0.41).
