Research on white organic light emitting diodes for lighting

对高效、高性能的有机发光二极管（oled）进行了实验研究。具有四个杂环的有机发光二极管显示出与太阳辐射光谱非常相似的超宽带。另一种在蓝色荧光发射层和黄色磷光发射层之间插入电荷产生层的OLED显示出120 cd/ a和50 lm/W的高效率。不仅成功地合成了聚合物，而且成功地合成了小分子多色光单分子。

Experimental work was done for organic light emitting diodes (OLEDs) which are highly efficient and functional. An OLED with four exciplexes showed a super-broad band quite similar to solar radiation spectrum. Another OLED with a charge generation layer inserted between blue fluorescence emitting layer and yellow phosphorescence emitting layer showed high efficiencies of 120 cd/A and 50 lm/W. Single molecule which emits multi-color light was successfully synthesized for not only polymer but also small molecule.
