摘要

采用新合成的有机材料硅烷衍生物作为发光物质制备了发蓝、绿光的薄膜电致发光器件。其结构为glass/ITO/PVK+SiH/Alq/Mg:Ag。分别测量了SCSSiH

聚乙烯咔唑(PVK)薄膜的光致发光光谱以及器件的电致发光光谱。其中SCSSiH薄膜的光致发光谱峰位置在496nm

有机器件的电致发光光谱的峰值为500nm。随着驱动电压的增加发光谱峰蓝移

其变化范围为25nm。在电流密度为89mA/cm

下器件的发光亮度可达810cd/m

。

Abstract

The organic thin film electroluminescence device with blue-green color using new organic material

silicon alkyl derivative(SCS-SiH)

was fabricated. The structure of the device is Glass/ITO/PVK+SCS-SiH/Alp/Mg:Ag. The photoluminescence(PL) spectra of the film (SCS-SiH and PVK) were measured

which were illuminated by the different excitation wavelength of 406nm and 340nm

respectively. The PVK shows an emission maximum at about 420nm that corresponds to the result measured by others

[7]

.The peak wavelength of SCS-SiH film is at 516nm with 70nm full width at half maximum(FWHM).The electroluminescence spectra were also measured and the peak wavelength of EL for the device is at about 500nm. It is found that the color of the device was blue-shifted with applied voltage

which may open vast vistas for full color flat panel display. The changing range is from 520nm to 495nm. The maximum brightness of the device is 810cd/m

with 25V(89mA/cm
