采用干冰微粒喷射法对ITO玻璃表面进行了清洁处理,并与浸泡式低频超声波湿法清洗的ITO玻璃进行了对比测量,结果表明:干冰微粒喷射法处理后,ITO薄膜表面的接触角减小,表面污染物颗粒数量下降,ITO薄膜表面上碳的含量较之未处理时降低了48.5%,锡、铟的含量分别增加了533.33%和267.57%,说明干冰微粒法对ITO薄膜表面的有机污染物和杂质颗粒的清洗效果超过了超声波湿法.此后,制备了干冰微粒法清洗ITO阳极的有机电致发光器件(OLED)器件,以及结构相同但ITO电极是用超声波湿法清洗的OLED器件,对这两种器件的参数进行了测量,其结果表明:干冰微粒喷射法清洗器件的启亮电压、亮度和电流效率与超声波湿法清洗的相比较均有所改善.
