Abstract :
Organic electroluminescent (EL) devices based upon the new lanthanide EL material Tb[Ph2P(O)NP(O)Ph2]3 (Tbpip3) are described. Several device structures are reported and the effect of charge transporting material and layer thickness on device performance critically assessed. Device performance is optimised in a three-layer structure containing TPD and Alq as the charge transport layers. This device has an efficiency of 0.7 cd A−1 at 20 cd m−2 at 25 V and 1 mA cm−2.
