Materials Design Concepts for Efficient Blue OLEDs: A Joint Theoretical and Experimental Study

Since their discovery, organic light emitting devices (OLEDs) have evolved from a scientific curiosity into a technology with applications in flat panel displays and the potential to revolutionize the lighting market. During their relatively short history, the technology has rapidly advanced, and device efficiencies have increased more than 20-fold, approaching the theoretical limit for internal quantum efficiencies.
