Efficient white organic light‐emitting devices with uncomplicated architectures are fabricated employing phosphorescent platinum(II) complexes containing extended π‐conjugated cyclometalated ligands as a yellow‐light source, and fluorescent material 9,10‐bis‐(β‐naphthyl)‐anthrene as a blue‐light source. Peak external quantum (power) efficiencies of 11.8 % (18.4 lm W –1 ) are demonstrated (see figure).
