Abstract
A high color purity hybrid electroluminescent (EL) device based on an organic dye and an inorganic phosphor has been developed. In this device, the organic dye is excited by the luminescence energy of the inorganic phosphor, and exhibits white luminescence from the three primary colors without a color filter. We developed the EL device using organic dyes that consist of coumarin 6 and a 4-(dicyanomethylene)-2-i-propyl-6-(1, 1, 7, 7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB)-doped phosphor layer. Furthermore, a RGB color device of the organic-dye dispersed inorganic EL device with red luminescence of high color purity was produced using a printing technique.
