| Research Abstract |
Powder EL is can be fabricated in the printing process with low cost by a simple printing process. However, there were some points to be improved to the characteristics of emission color and luminance. In this study, we examined the mechanism of light emission about the organic dye-doped powder inorganic EL. As a result, by adding in appropriate dye doping, were able to obtain only the emission from the organic dye with high luminance. We indicated the white-light emission for lighting, which was contained two organic dyes in the phosphor layer indicating the high color rendering with Ra=89.
