Abstract

The solution/evaporation hybrid processed organic light emitting devices composed of newly developed host material CzDBS, green PG-02 dopant, and orange PO-01-TB and PO-06 dopants are studied. Orange, green and two-peak white light emitting devices were fabricated by using spin coating of HIL, HTL and emission layers followed by thermal evaporation of ETL and cathode. The orange devices achieved efficacies of 26.9 cd/A and 14.6 lm/W at the brightness of 1538 nits. The green devices, on the other hand, achieved efficacies of 31.3 cd/A and 19.7 lm/W at the brightness of 1590 nits. The two-peak white devices, composed of blue FIrpic and orange PO-01-TB, achieved efficacies of 36.9 cd/A and 18.4 lm/W at the brightness of 1150 nits.
