摘要
自从1987年邓青云博士发明有机发光二极管(OLED)以来,相关领域的研究蓬勃兴起。近年来,OLED已在中小尺寸显示领域得到广泛的应用,并逐步进入大面积显示和照明等领域。有机发光技术的不断发展,对有机发光材料与器件的研究提出了更高的要求。本报告综述了近年来国内外有机发光材料与器件研究领域关注的重要问题和其中的主要进展。随着OLED技术的深入发展,该领域的研究体现出基础理论与技术创新并重的特点,在材料与器件技术和有机半导体传输理论方面都取得了丰硕成果。在材料与器件技术方面,本文主要综述了新型磷光材料分子设计,新型荧光材料及其发光机理研究,白光器件技术,湿法制备技术及柔性制备技术等几个方面的最重要进展。在有机半导体传输理论方面,本文主要综述了从分子堆积、薄膜无序度及掺杂等角度对有机半导体传输理论进行的研究工作。最后,报告对国际有机显示技术和有机照明技术的产业现状及发展方向进行了概述。
Since the invention of organic light-emitting diodes(OLEDs) by Dr. CW Tang in 1987, researches in related fields have been developed rapidly. Now, small to medium size OLED displays have already been commercialized. Large OLED TVs and OLED lightings have also emerged in real applications. The further development of the OLED technology calls for intensive research on organic light-emitting materials and devices. This report reviewed the most focused issues as well as the main progress in the field of OLEDs in the recent years. It is shown that researchers have paid attentions to both technical innovations and theoretical researches, such as the design of new molecules, developing of new device technology, and understanding of light-emitting and transporting mechanisms of organic semiconductors.The developing trends of organic light-emitting materials and devices are summarized as follows: 1) molecular design for high performance phosphorescent materials; 2) novel fluorescent materials and their light emitting mechanisms; 3) new technologies for high performance white OLEDs; 4) new technologies for solution-processed devices and flexible devices; 5) the influences of molecular packing, disorder and doping on the charge transporting properties of organic semiconductors. Moreover, the current situations and developing trends of international OLED display and lighting industries are discussed.
