| 摘 要： | 制作了一种以Al为金属反射膜和金属半透膜的微腔有机电致发光器件(OLED)。器件结构是:Al/MoO3/NPB/ADN∶TBPe∶DCJTB/Alq3/LiF/Al。设计了五种厚度的金属Al阳极半透膜器件,Al半透膜的厚度依次为:12nm,13nm,14nm,15nm,16nm。通过调节阳极Al半透膜的厚度,改变微腔的光学长度,研究微腔效应对器件性能的影响。利用Al半透膜阳极厚度的变化,调整微腔器件的光学长度,发光效率和色纯度也随之变化。当Al半透膜为12nm时,器件在11V获得最高亮度3 381cd/m2,最高效率为2.01cd/A,色坐标为(0.33,0.39)。实验表明,合理利用微腔效应,可提高以Al为阳极器件的色纯度,并保持一定的发光效率。

| Abstract: | A microcavity organic light-emitting diode(OLED) device with the structure of Al/ MoO3/ NPB/ ADN∶TBPe∶DCJTB/ Alq3/ LiF/ Al is fabricated using Al as the metal reflective film and metal semipermeable membrane.Five kinds of devices with Al anode semipermeable membrane designed for different film thicknesses as: 12 nm,13 nm,14 nm,15 nm,16 nm,and the effects on the performance of OLED micro-cavity are researched.The results show that both the luminous efficiency and color purity change with the optical length of the micro-cavity.When the thickness of Al semipermeable membrane is 12 nm,the device can obtain the maximum brightness of 3 381 cd/m2,highest efficiency of 2.01 CD/A,and color coordinates of(0.33,0.39) at 11 V.Therefore,using microcavity effect reasonable can improve the color purity of the device and maintain a certain luminous efficiency. |
