More Information
Summary:An electroluminescent device having a phosphor layer including a phosphor material and a pair of electrodes for applying a voltage to the foregoing phosphor layer wherein an acetylacetonato complex salt is included in the phosphor layer to realize an electroluminescent device with high luminance. Further, the EL device realizes an electroluminescent device with higher luminance by constructing the foregoing phosphor layer so as to contain acetylacetonato complex salt, in which ligands coordinate with a trivalent metal atom, particularly a metal atom of Group III or Group XIII as the foregoing acetylacetonato complex salt.
