摘要

为了提高掺杂型有机电致发光器件(OLED)中主体发光材料与客体荧光染料间能量传递的效率

2-对联苯-8-羟基喹啉锌(Zn

)作为NPB : DCJTB掺杂体系的能量助传递剂

制备了结构如:ITO/NPB/NPB : DCJTB/Zn

/BCP/Al的有机电致发光器件。助传递剂Zn

的加入

能够两次利用Frster能量转移

实现NPB向DCJTB级联式的能量传递过程

提高低浓度时掺杂染料DCJTB红光发射的纯度;此外

还探讨了三者间能量传递的有效距离

即当助传递剂与掺杂体系的距离在小于10 nm的范围内

其参与能量传递的效率随着距离的增加而逐渐下降。

Abstract

In order to increase the energy transfer from host to guest in doping organic light-emitting diodes (OLEDs)

bis(2-biphenyl-4'-yl-8-quinolinolato)zinc Zn

was synthesized and used to assist the energy transfer from N

N'-bis-(3-naphthyl)-N

N'-biphenyl-(1

1'-biphenyl)-4

4'-diamine (NPB) to red fluorescent dye 4-(dicyanomethylene)-2-t-butyl-6(1

7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB). OLED with the structure of ITO/NPB/NPB:DCJTB/Zn

/BCP/Al were fabricated. Without the Zn

layer

incomplete energy transfer from NPB to DCJTB led to both emission from host and guest. After Zn

was added in to the device

only red emission of DCJTB material was detected in electroluminescence spectra. The efficient emission of DCJTB is achieved via energy transfer with a cascade process from NPB to Zn

and then to DCJTB

which results in a complete energy transfer from host to guest. In particular

as the concentration of DCJTB is only 0.5%

red-light-emitting OLED is successfully fabricated using Frster transfer theory at twice. Traditionally

the fabrication of OLED using the assistance material needs thermal evaporation with three sources. However the red OLED only needs two sources

which is very useful in application in the future. In addition

by varying the distance between Zn

and the doping system

the efficiency of energy transfer is changed. When the distance is below 10 nm

has an influence on the energy transfer of the doping system. And the longer the distance is

the lower the efficiency is.
