Abstract

We report on the application of vary thin molybdenum trioxide (MoO3) film deposited by spin-coating from dilute aqueous solution to the organic light-emitting diodes (OLEDs). The device characteristics with solution-processed MoO3 were drastically improved in comparison with the device without MoO3 buffer layer. Luminance and electroluminescent (EL) efficiency were identical to the devices with poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) or vacuum-deposited MoO3 buffer layer. Also, the barrier height at interface of indium-tin-oxide/organic layer is lowered with insertion of spin-coated MoO3. Solution-processed MoO3 from dilute aqueous solution is promising for the buffer layer in the OLEDs.
