【Abstract】 Based on the measurement of the contact angle of differently treated ITO, the surface energy and polarity were calculated using the harmonic mean method. It is found that the surface energy and polarity of the ITO varied considerably with the surface treatments, and mainly through its polar component. Oxygen plasma treatments induced the highest surface energy and the highest polarity. This is essential for optimizing the properties of the ITO/organic layer interface and improving the performance of organic light emitting device.更多还原
