Abstract： High-efficient organic light-emitting diodes (OLEDs) with indium-tin-oxide (ITO) anode treated by KMnO4 solution are demonstrated. The performance of the OLEDs depends on the concentration of KMnO4 solution and time of ultrasonic treatment. The OLED whose ITO anode was treated by ultrasonic in KMnO4 solution with concentration of 50mg/L for 15min displays the best performance. It has higher electroluminescent brightness and lower turn-on voltage than those of traditional devices. In particular, its efficiency can be increased by approximately 40%. The surfaces of the ITO anode with and without treating are analysed by scanning electron microscopy.
