A powder electroluminescent (EL) device can be fabricated by a simple printing process. The present applications of these devices are restricted to providing low-intensity backlighting. In order to realize a lighting system, it is necessary to develop EL devices that have white luminescence. It was believed that it is difficult to realize white luminescence in powder-type inorganic EL devices. However, we have produced high-luminance organicdye-dispersed powder EL devices. Moreover, we have produced high color rendering white-light-emitting organic-dye-dispersed powder EL devices that consist of the three primary colors. The operating conditions for the organic-dye-dispersed powder EL devices are the same as those for a conventional powder EL device. The film thicknesses of both the dielectric and phosphor layers were approximately 30 μm. We have manufactured a novel white-light-emitting powder EL device with a new hybrid structure by doping the phosphor layer with organic fluorescent dyes.
