Tunable near-UV microcavity organic light-emitting diodes (OLEDs) that emit in the deep blue and ultraviolet light region have been developed using a novel approach. These devices address the growing need for portable compact near-UV sources for analytical tools as well as various biomedical and forensic applications. These are among the first OLEDs that emit in the near-UV region. In this new approach, the team tuned the thickness of the spacer layer of a nanometer wide microcavity, allowing them to tailor each individual OLED in the array to the desired narrow-band emission.
Valley High School's Science Bowl Team, which won the 2015 Ames Laboratory/Iowa State University Regional Science Bowl was featured on the WHO-TV news recently. The story talked with students and coach Nathan Speichinger about the competition and showed the team practicing for the upcoming National Science Bowl to be held April 39-May 5 in Washington, D.C.
