Iridium complexes have a wide range of applications such as photocatalysts to reduce carbon dioxide [1], imaging reagents for living cells [2], and oxygen sensors [3]. In particular, organic light emitting diodes (OLED) is one of important industrial application for iridium complexes, due to their high phosphorescent efficiency at ambient temperature [4,5]. OLEDs have many advantages, including self-emission (no backlight required), an almost 180 wide view angle, light weight, thin (<2 mm), quick response (1,000 times faster than LCD), high contrast, and can be fabricated on flexible plastic substrates.In 1987, Tan et al. reported the potential of OLEDs using tris (8-hydroxyquinolinato) aluminium (III) (Alq 3 ) [6]. Before them, the OLED device has simple configuration that has single organic crystal sandwiched by two electrodes. They introduced concept of OLED device configuration composed of multiple thin layers (Fig. 11.1). Here, each layer has an exact function, such as charge transporting and emitting abilities. The external efficiency of this OLED device was 1 %, which meant an internal efficiency of 5 %, because the output efficiency from the device was approximately 20 % [7]. After charge (hole and electron) injection into the emitting layer, 25 % singlet and 75 % triplet excitons are generated by charge recombination. Therefore, the only usable amount of fluorescence is 25 %. If phosphorescent materials can be used, then the 75 % triplet excitons are usable. In addition, the triplet excited state has lower energy than the singlet excited state; therefore, there is a chance that intersystem crossing of singlet excited state to the triplet excited state could occur.

This paper outlines the development status, issues, and applications of several solid electrolyte electrochemical devices currently being developed by Ceramatec and its partners. Ceramatec and its commercial partner Air Products and Chemicals, Inc., (APCI) have successfully developed and demonstrated an electrochemical device that utilizes a ceria-based, solid electrolyte to separate oxygen from air [1,2]. Other oxygen separator projects utilize ion transport membrane(s) (ITM) composed of mixed ionic and electronic conductors to transport oxygen ions across the membrane by means of a pressure differential driving force to generate high purity oxygen or a chemical reaction driving force to produce synthesis gas from methane (ITM Syngas).Ceramatec, in partnership with SOFCo, demonstrated kilowatt class solid oxide fuel cell (SOFC) stacks operating on a variety of fuels such as pipeline natural gas and reformed diesel. Ceramatec is presently working with Cummins and SOFCo to develop low cost modular fuel cells under the Department of Energy's Solid-state Energy Conversion Alliance (SECA) initiative. Some of Ceramatec's other programs are focused on development of gallate electrolyte based fuel cells [3] and metallic bipolar plates [4] for lower temperature operation.

A new class of microwave and millimeter-wave amplifiers, based on the deflection of collimated microscopic electron beams with high-current density and low voltage from field-emitter arrays, was analyzed. The deflection concept may be applied in two ways; as microelectronic amplifiers or as bunched beam cathodes to power conventional amplifier configurations such as klystrodes and traveling wave tubes. We found that the frequency fT, at which the short-circuit current gain attains unit magnitude, depends only on the electron beam energy, current density, and emittance, and is independent of beamwidth and total current. The results indicate that field-emitter arrays have the potential of making wideband deflection amplifiers at frequencies up to tens of GHz.
