AbstractSince the invention of organic electroluminescent devices, a great deal of effort has been made to improve their performance. Reducing the barrier and optimizing charge injection is crucial for efficient and bright Organic Light Emitting Diodes (OLEDs). We report the performance of OLEDs with ITO/TPD/Alq3/Al structure by inserting LiF both at electrode-organic interfaces and organic-organic interface. We elucidate the mechanism of the LiF buffer layer inserted at different interfaces. The device with LiF as a cathode injection layer shows improved luminescence and steeper IV characteristics.

Organic Electroluminescent

A new compound, 2,3,2',3'-Tetraphenyl-[6,6']-biquinoxalinyl was synthesized. Its structure was determined by mass spectrometry and elemental analysis. Organic electroluminescent devices using this compound as electron-transporting layer were fabricated and electroluminescent properties were studied. It was demonstrated that this compound has excellent electronic transmission performance in organic light-emitting diodes (OLED).
