![عکس صفحه اول مقاله: Improved performances of organic light-emitting diodes with mixed layer and metal oxide as anode buffer Improved performances of organic light-emitting diodes with mixed layer and metal oxide as anode buffer](/preview/png/748436.png)
We fabricated organic light-emitting devices (OLEDs) employing 2-methyl-9,10-di(2-naphthyl)-anthracene (MADN) as hole-transport material (HTM) instead of commonly used N,N′-bis-(1-naphthyl)-N,N′-diphenyl,1,1′-biphenyl-4,4′-diamine (NPB). After inserting a 0.9 nm thick molybdenum oxide (MoOx) layer at the indium tin oxide (ITO)/MADN interface and a 5 nm thick mixed layer at the organic/organic heterojunction interface, the power conversion efficiency of the device can be increased by 4-fold.
► We replaced NPB with MADN as HTM in OLEDs, in order to obtain high current efficiency.
► We inserted both thin MoOx and mixed layers in the OLEDs in order to reduce the driving voltage.
► Other color OLEDs with high power efficiency can also be obtained by this method.
