Metal/AlQ3 interface structures
Abstract
X-ray photoelectron core level spectroscopy has been used to probe the buried metal (Au, Ag, Mg, Mg:Ag alloy)/AlQ3 interface structures from working organic light-emitting diodes. It is found that there is no chemical reaction between (Au,Ag)/AlQ3 interfaces, while there is a significant reaction/diffusion at (Mg,Mg:Ag)/AlQ3 interfaces. The reaction is AlQ3 oxidation-reduction reaction in nature, and is well explained by thermodynamic …
