Abstract

A diode-addressed color display comprising an UV-diode and a phosphor of the general formula [Eu(diketonate).sub.a X.sub.b1 X'.sub.b2 ], wherein X=pyridine or a unidentate pyridine derivative and X'=2,2'-bipyridine or a 2,2'-bipyridyl derivative and 2a+b.sub.1 +2b.sub.2 =8, is characterized by a high quantum efficiency and a high extinction coefficient in the near-UV wavelength range and enables a color-sensitive image reproduction to be achieved.
