논문 초록 (Abstract)
Nanoparticle scattering layer based on polymer-metal oxide composite is successfully introduced to enhance the light extraction efficiency of organic light emitting diodes (OLEDs). We find that the density and t he distribution of nanoparticles is the key factor to maximize the light extraction efficiency of pristine OLEDs by out-coupling the unusable light with the scatteringfilm. In our experiment, 71 wt% of Al2O3 mixed with polymer matrix shows the increase of light extraction efficiency of 40%. This method is expected to play a critical ro le to create the low-power OLED application such as OLED lightings wit h simple fabrication process and low cost. (C) 2015 Optical Societ y of America
