Efficacious white OLED devices have been developed for lighting applications. The high efficacy was achieved by incorporating two key technologies: a 3-unit tandem hybrid device architecture and a random scattering light extraction enhancement struct

We have developed new iridium (III) complexes having coumarin, including its aza-analogue structure, in their ligands. These Ir complexes are highly emissive with colors ranging from yellow, yellowish-green to green. Electrochemical analysis shows th

Most successful recordable-CD media (CD-R) to date are based on a design suggested by Hamada et al(1). In this design the CD-R disc is constructed using a polycarbonate substrate, a lightly absorbing recording layer, and a gold reflector. The recordi

For organic light-emitting-diode (OLED) lighting to be successful, it is critical that it be properly positioned in the marketplace. It is also critical that both the performance and cost be competitive against other lighting technologies in the sele

We demonstrate a broadband-emitting microcavity-OLED device by applying a light-scattering layer to a microcavity device to integrate its angular-dependent narrow-band emission and to detrap shorter wavelength light from the substrate. The luminous e

Efficient thin film CdS/CdTe solar cells can be prepared by the close-spaced sublimation technique onto soda-lime glass coated with either indium tin oxide or tin oxide. Oxygen is needed to enhance the p characteristics of CdTe; a high substrate temp

Solid-state photovoltaic cells are feasible devices for converting solar energy directly to electricity. Recent cost reductions have spurred an incipient industry, but further advances in materials science and technology are needed before photovoltai
