英文摘要	An efficient non-doped blue organic light-emitting diode with several-nanometer-thick easy-to-aggregate fluorescent material perylene is reported in which two thin layers of perylene as blue emitters are located at both the sides of ambipolar material, 4,4 '-N,N '-dicarbazole-biphyenyl (CBP), and the aggregation behavior of perylene in films is prevented. The maximum luminance and external quantum efficiency are 16 000 +/- 600 cd/m(2) and 3.0% +/- 0.02% (3.70 +/- 0.03 cd/A), respectively. Commission Internationale de l'Eclairage co-ordinates are basically x = 0.14 and y = 0.15. Although Foster energy transfer from CBP to perylene is efficient, the carrier confining induced exciton direct formation mechanism is considered to dominate the process of electroluminescence.
