摘要: We report the change of surface electronic structure indium–tin–oxide (ITO) as a function ultraviolet (UV)–ozone treatment time. The voltage organic light emitting diodes at current density 100 mA/cm2 was reduced time using UV–ozone lengthened. X-ray photoelectron spectroscopy results showed that relative concentration carbon atoms decreased, but oxygen increased relatively with treatment. This led to increase in ITO work via reduction operation voltage.
