Highly Efficient RGB Emissions from Polymer Light-emitting Diodes using Phosphorescent Polymers

摘要

We report on the experimental demonstration of highly efficient red, green and blue emissions in polymer light-emitting diodes where novel phosphorescent polymers were used as the emissive materials. The phosphorescent polymers consist of hole-transporting units and phosphorescent units. External quantum efficiencies for the red and green emissions exceeded 5%.
