Solution-based molybdenum oxide as a good hole injection layer in organic light emitting diode

Molybdenum oxide thin film prepared from a aqueous solution as a good hole injection layer (HIL) inorganic light emitting diode. Molybdenum Oxide can be well substituted to Poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) which is a conventional HIL. In this report variousconditions of thin film fabrication were done such as; thickness, annealing temperature, annealing atmosphere, and UV Ozone treatment. The performance of organic light emitting diode (OLED) fabricated using molybdenum oxide showed a good results against one fabricated using PEDOT:PSS. Chemical and electronic structure of the layer was indicated by X-ray/ultraviolet photoelectron spectroscopy (XPS/UPS).
