Researchers from the University of Berkeley found a new way to process white OLEDs for solid state lighting. They are using Red, Blue and Green Phosphorescent OLED materials that usually suffer from interference between them when trying to create white light. But the researchers used polymer nanoparticles (iridium-based) to house the OLED materials, and these are used as a "do not disturb" sign, isolating guest molecules from one another, and enabling them to emit light without interactions from other colors.
