【摘要】：同时实现简单结构、高显色指数(color rendering index,CRI)以及低成本的WOLED(white organic light-emitting diode,WOLED)具有很大的挑战。本研究采用m-MTDATA(4,4′,4″-tris[3-methylphenyl-(phenyl)aminotriphenylamine,m-MTDATA)和TPBi(2,2′,2″-(1,3,5-benzenetriyl)tris-[1-phenyl-1H-benzimidazole,TPBi)形成的发射光谱较宽的黄绿光激基发射,同时结合电子传输材料Bepp2(Bis[2-(2-hydroxyphenyl)-pyridine]beryllium,Bepp2)的蓝光发射,通过合理的器件结构设计实现激子在不同发光区域中的合理分布,最终实现了最大CRI为80、结构简单、且成本低的WOLED.这种新型的器件设计理念为发展结构简单、高性能的WOLED提供了好的指导,对于WOLED的商业化照明具有很强的现实意义。
[Abstract]:At the same time, the realization of simple structure, high color rendering index (color rendering) and low cost wand (white organic light-emitting (de) have great challenges. In this study, a yellowish photoluminescence emission from m-MTDATA (4-methylphenylphenyl- (phenyl) aminotriphenylamine-m-MTDATA) and TPBi (2Pbi (2zilenetriyl) tris- [1-phenyl-1H-benzimidazoleTPBi]) was studied, and the blue emission of Bepp2 (Bis [2- (2-hydroxyphenyl) -pyridine] berylliumepp2) was studied. The reasonable distribution of excitons in different luminescence regions is realized by reasonable device structure design. Finally, the WOLED with the maximum CRI of 80, simple structure and low cost is realized. This new device design concept provides good guidance for the development of WOLED with simple structure and high performance, and has a strong practical significance for commercial lighting of WOLED.
