【摘要】 透明有机电致发光（TOLED）是有机电致发光领域里的一个热门方向。透明OLED可以用在头盔显示，挡风玻璃式显示以及类似的场合,还可以利用堆栈式结构的透明有机电致发光（TOLED）实现高分辨率的彩色显示。本文主要是利用LaB₆来制备有机电致发光器件的透明阴极，本文采用两种加热的方法来制作：分别是利用LaB₆阴极和氧化物阴极作为轰击电子源来制作LaB₆透明阴极。论文首先对有机电致发光（OLED）的发展历史作了一个简要的回顾，对OLED的发光机理和彩色方案进行了阐述；接着，第二章阐述了论文所要运用的理论知识，主要是透明有机电致发光（TOLED）的发光机理、LaB₆的特性、氧化物阴极的理论等；第三章阐述了如何制作LaB₆透明阴极，文中介绍了两种加热的方法制作LaB₆薄膜；第四章是对试验的结果进行分析，主要是其导电性能和光谱透过率，并与Mg：Ag合金和ITO制作透明阴极进行了比较；第五章是对所作的工作的总结。更多还原

【Abstract】 Organic light emitting diode （OLED） consists of a number of ultra-thin organic layers between two electrodes. Under low applied voltage, the recombination of carriers coming from cathode and anode can produce intense light output. Organic light emitting diode has the merit of LCD and CRT. So it’s considered as the best flat-panel display in the 21st century. Transparent organic light emitting diode （TOLED） is expected to be useful in high-resolution full-color displays, as well as for helmet-mounted, windshield-mounted, or other "head-up" display applications. This paper discusses how to make transparent cathode of OLED used LaB₆ and oxide cathode.The first chapter mainly introduces the history and the principle of OLED, and how to get full-color.The second chapter provides some principles, which are necessary for making TOLED.The third chapter is the most important; it mainly discusses how to make the transparent cathode of OLED used LaB₆ cathode and oxide cathode.And the following chapter discusses the result of the experiment; it mainly discusses the transparency and the resistance of LaB₆, and it also compare the cathode used LaB₆ with the cathode used Mg:Ag and ITO.And the last chapter is a conclusion for the research and the experiment.更多还原
