Abstract
(Figure Presented). Phosphorescent light-emitting transistors, in which light emission from singlet and triplet energy levels is harvested using solution-processed materials (see figure), are presented. While a green phosphorescent dendrimer exhibits an external quantum efficiency of 0.45% at 480 cd m-2, a red polymer/phosphorescent small-molecule blend produces a brightness exceeding 30 cd m-2 with a relatively high hole mobility of 2.5 × 10-2 cm2 V-1 S-1.
