Charge injection/blocking layers play important roles in the performances of organic electronic devices. Their incorporation into organic light emitting transistors has been limitted, due to generally high operating voltages (above 60 V) of these devices. In this work, two hole blocking mols. are integrated into tris-(8-hydroxyquinoline) aluminum (Alq3) based light emitting transistors under operating voltage as low as 5 V. The effects of hole blocking and electron injection are decoupled through the differences in the energy levels. Significantly improved optical performance is achieved with the mol. of suitable energy level for electron injection. Surprisingly, a decreased performance is observed in the case of another hole blocking mol. evidencing that charge injection overweighs charge blocking in this device architecture.
