Description: This image shows PNNL scientist James Swensen demonstrating the workings of a higher-efficiency, charge-balanced, blue phosphorescent organic light emitting device (OLED). These multi-layered devices produce light by running an electrical current through a specially engineered host material into which light-producing phosphorescent molecules are embedded or "doped". The white light envisioned for large-scale applications, such as rooms and buildings, consists of red, green and blue light.
