摘　　要：用一种特制的纳米研磨粉磨擦方法处理ITO表面,用扫描探针显微镜研究了ITO表面形貌,发现ITO表面尖峰明显减少,表面粗糙度降低;研究了ITO处理与没做处理的双层结构有机电致发光器件,发现ITO处理的器件在亮度和效率方面都有明显提高。分析了器件性能提高的原因,认为是由于ITO处理的器件提高了注入载流子并且降低了界面势垒。The influences of surface treatments of indium-tin-oxide （ITO） anodes on the performance of OLED devices were investigated. This surface treatment is mechanical processes using a novel nanometer powder. Their surface morphology was measured by scarming using an AFM （atomic force microscope）. The number and size of spike was reduced and regulation of ITO was enhanced; brightness and efficiency of devices were obviously increased. This novel way for ITO surface treatment by mechanical processes was proven to be effective.
