In this paper, we report that by inserting a nanoparticle diffuser film by spincoating between the OLED and the glass substrate as the scattering structure. The external quantum efficiency and the cd/A efficiency of conventional bottom emitting OLEDs can be significantly improved 1.96×for quantum efficiency and 2.04× for cd/A efficiency. The fabrication of nanoparticle diffuser film is simple and attractive for OLED application and mass production.
