摘要
在有机电致发光器件制备工艺中,可以通过控制蒸发速率获得均匀致密的有机膜,在其中引入空穴传输层NPB能改善阳极与有机层的接触,提高载流子的注入和平衡水平,使激子复合率得到有效改善,从而大幅提高器件的发光特性。
In the course of OLED preparation, the even and compact organic film can be obtained by controlling the speed of evaporation. The hole transport layer NPB is drawn into OLED, which can improve the contact of anode with organic film. At the same time, the level of current carrier injection and balance can be improved. Thereby the complex rate can be improved and the characteristic of luminescence can be raised.
