| 摘 要： | 成功制备了铕配合物的微腔结构有机发光二极管(0LEDs)，其发射层采用质量比为1：3的空穴传输材料(TPD)和电子传输材料(Eu(DBM)3bath)的混合层。该器件实现了Eu^3 高色纯度红光发射，其色坐标为(x=0．651，y=0．338)；并克服了微腔器件的发光颜色随探测角度增大而变化的缺点。在微腔器件中，最大亮度在19V时达到1160cd／m^2；在高电流密度时的EL效率得到明显提高。 |

| Abstract: | Organic light emitting diodes with microcavity structure have been fabricated. Comparing of the optimized cavity and non-cavity devices, the EL performances of cavity device was improved significantly. The pure-red emission of Eu 3+ was observed, and the CIE coordinates were about (x=0.651, y=0.338). Because of the sharp-band emission of Eu 3+ complex, the defect of OLEDs with microcavity structure, causing a blue-shift of emission peak with increasing emission angle, was weakened. The maximum brightness of 1 160 cd/m 2 was achieved at 19 V, and the efficiency was enhanced at high current density. |
