Improved hole-injection contact for top-emitting polymeric diodes

In this letter, an efficient hole-injection contact was achieved for the top-emitting polymeric light-emitting diodes PLEDs . The anode has a structure of metal/molybdenum oxide/ poly 3,4-ethylenedioxythiophene poly styrenesulfonate PEDOT:PSS . It has been found that hole injection was significantly improved by inserting a thin layer of MoO3 between… (More)
