Efficient excimer emission is demonstrated in white organic light‐emitting diodes (see figure) based on platinum(II)[2‐(4′,6′‐difluorophenyl)pyridinato‐N, C 2′ )](2,4‐pentanedionato) utilized in devices incorporating the novel host material 2,6‐Bis( N ‐carbazolyl)pyridine (26mCPy). External quantum (power) efficiencies of 15.9 % (12.6 lm W –1 ) are realized at 500 cd m –2 .
