【摘要】：有機發(fā)光二極管(OLED)在新型顯示和固態(tài)照明等領域有著廣泛的應用潛力,在可穿戴設備、手機、電視等顯示產品上已經(jīng)實現(xiàn)了較大規(guī)模的商業(yè)化應用,未來預計在柔性顯示領域將具有更為突出的應用前景.為進一步降低OLED材料與器件的制備成本,近些年來,大量的研究聚焦于開發(fā)不含有稀有金屬、兼具低成本和高性能優(yōu)勢的OLED材料與器件.本文綜述了基于純有機半導體材料、利用層間電荷轉移來構筑OLED的研究進展,著重討論了有機平面pn異質結發(fā)光二極管(pn-OLED)概念的提出,以及相應的有機半導體材料與器件等方面的進展,并對該類型器件目前發(fā)展中遇到的問題,以及將來在發(fā)光晶體管、電泵浦激光器等領域潛在的應用進行了討論.
[Abstract]:Organic light-emitting diode (OLED) has wide application potential in new display and solid-state lighting. It has been widely used in wearable devices, mobile phones, TV and other display products. It is expected that there will be more prominent application prospects in the field of flexible display in the future. In order to further reduce the preparation cost of OLED materials and devices, in recent years, a lot of research has focused on the development of OLED materials and devices that do not contain rare metals and have the advantages of low cost and high performance. In this paper, based on pure organic semiconductor materials, the research progress of using interlayer charge transfer to construct OLED is reviewed. The concept of organic plane pn heterojunction light-emitting diodes (pn-OLED) is emphatically discussed. The development of organic semiconductor materials and devices is also discussed. The problems encountered in the development of this type of devices and their potential applications in the field of luminescent transistors and electrically pumped lasers are also discussed.
