摘要

以典型发光材料联苯乙烯衍生物(4

4'-bis(2

2'-diphenylvinyl)-1

1'-biphenyl

DPVBi)和红荧烯(5

12-tetraphenylnaphthacene

Rubrene)分别为蓝色、橙色发射体

通过在DPVBi中插入一层超薄Rubrene制备了结构简单的非掺杂型白色有机电致发光器件

得到了低压启动、效率和色度俱佳的白色发光器件。器件启亮电压为3.1 V

最高电流效率为6.7 cd/A(流明效率5.5 lm/W或外量子效率2.8%)

器件色坐标达到理想的白平衡点(0.33

0.33)。理想白光的获得归因于通过调整NPB/DPVBi界面到Rubrene的距离

实现了从DPVBi到Rubrene能量传递的最佳比例。

Abstract

By using typical luminescent materials

4'-bis(2

2'-diphenylvinyl)-1

1'-biphenyl (DPVBi) and 5

12-tetraphenylnaphthacene (Rubrene) as a blue and orange emitter

respectively

a highly efficient bright nondoped white electroluminescent device with low driving voltage and ideal chromaticity is fabricated. The turn-on voltage

maximum current efficiency are 3.1 V

6.7 cd/A (luminous efficacy of 5.5 lm/W

external quantum efficiency of 2.8%)

respectively. Commission Internationale de l'Eclairage (CIE) co-ordinates are at ideal equal-energy white point (0.33

0.33). The achievement of excellent white emission is attributed to realizing perfect ratio of energy transfer from DPVBi to Rubrene by tuning distance from NPB/DPVBi interface to Rubrene.
