分别采用NaOH和HCl溶液对废旧氧化铟锡(ITO)基板进行再生处理
用原子力显微镜(AFM)观测了处理后的ITO表面形貌
并基于再生处理过的ITO制备了有机电致发光器件(OLED)
系统研究了器件的性能。结果表明
上述方法可以有效去除废旧ITO残留的铝电极并改变其表面的化学结构
提高了器件的特性
尤其以NaOH单次处理最为有效。以此制备的OLED器件电流效率达到12.08 cd/A
较之未回收利用的新ITO所制备的器件提高了14.7%;外量子效率达到5.23%
提高了11.7%。另外
经不同方法处理后
器件中生色团与生色团之间、生色团与助色团之间的空间位阻增大
器件发光光谱肩峰效应增强。
NaOH solution and HCl solution were used to recycle the used indium-tin oxide (ITO) substrate. The treated surface was then observed by using atomic force microscopy (AFM)
while organic light-emitting devices (OLEDs) were fabricated with the recycled ITO to study the influence of reutilization on the performance of OLED. The results show that such treatments can efficiently remove the residual aluminum electrodes on the used ITO and change the chemical composition of the surface
especially by the NaOH treatment. OLED based on such recycled ITO can achieve a current efficiency of 12.08% with an increase of 14.7% compared with that based on new ITO
while the external quantum efficiency reached 5.23% with an increase of 11.7%. In addition
the sterically hindered between the chromophores and between chromophore and auxochrome increased
resulting in the enhanced side-band effect in the electroluminescence spectrum of the device when ITO was processed by different methods.
