文摘

Highly efficient phosphorescent white organic light-emitting diodes (PHWOLEDs) were developed using a solution processed 9-(3-(dibenzo[b,d]furan-2-yl)phenyl)-9H-carbazole (CzDBF) host material. Blue and orange phosphorescent emitters were doped into the CzDBF host and balanced blue and orange emission was obtained. High quantum efficiency of 13.2 % was achieved in the solution processed PHWOLEDs using the CzDBF host material.
