Abstract: Blue organic light emitting devices(OLEDs) with Alq, PBD, BBOTor F-OXDas the electron transport layer were fabricated by a high-vacuum multisource-type organic molecular deposition system. The effect of various electron transport layers on the performances of OLEDwas studied. The result indicates that the performances of devices with electron transport layer added between emitter and cathode are increased greatly. It is found that device: ITO/TPD/PPCP/Alq/Al is optimal in structure compared with other devices. Its turn-on voltage is 4 V. Its maximal brightness is 2000 cd/m 2 and its maximal efficiency is 0.36 lm/W.

Key words: Multilayers device, Electron transport layer, Blue organic light emitting device
