Abstract

Abstract An effective anode buffer layer is demonstrated by aqueous solution-processed indium trichloride (sInCl3) in simplified phosphorescent organic light emitting diodes (PhOLEDs). The hole injection is improved in sInCl3 based PhOLEDs exhibiting better performance with decreased driving voltage, increased power efficiency compared to the traditional ultraviolet-ozone (UV-Ozone) treated ones. Then, the mechanism for the enhanced hole injection is investigated. Better electrode contact is found in sInCl3 based hole dominated devices. Higher work function (∼0.60 eV) is detected on the sInCl3-ITO anode and stable In Cl bonds are formed on its surface compared to the UV-Ozone treated one according to the photoelectron spectroscopy.
