“…This will be an experimental review, focusing on new concepts and developments since the last such report in this journal (5) and in others (6,7). The reader is referred to several excellent theory reviews (8,9,10,11,12) that are still largely up to date. There is one new development of interest to our present purpose however, namely the realization that any string theory contains several and perhaps a large number of axion-like particles, although they are extremely light, of order neV.…”

Four decades after its prediction, the axion remains the most compelling solution to the Strong-CP problem and a well-motivated dark matter candidate, inspiring a host of elegant and ultrasensitive experiments based on axion-photon mixing. This report reviews the experimental situation on several fronts. The microwave cavity experiment is making excellent progress in the search for dark matter axions in the microelectronvolt range and may be plausibly extended up to 100 µeV. Within the past several years however, it has been realized that axions are pervasive throughout string theories, but with masses that fall naturally in the nanoelectronvolt range, for which a NMR-based search is under development. Searches for axions emitted from the Sun's burning core, and purely laboratory experiments based on photon regeneration have both made great strides in recent years, with ambitious projects proposed for the coming decade. Each of these campaigns has pushed the state of the art in technology, enabling large gains in sensitivity and mass reach. Furthermore each modality has also been exploited to search for more generalized axion-like particles, that will also be discussed in this report. We are hopeful, even optimistic, that the next review of the subject will concern the discovery of the axion, its properties, and its exploitation as a probe of early universe cosmology and structure formation.

A series of triarylaminooxadiazole-containing tetraphenylsilane light emitting polymer (PTOA) and poly(2-methoxy, 5-(2 0 -ethyl-hexyloxy)-p-phenylene-vinylene) (MEH-PPV) based white light emitting polymer devices (PLEDs) were fabricated to study blue and orange-red emitter composition and light emitting layer processing effects on white emission electroluminescence properties. Color purity, current turn-on voltage, brightness, and current efficiency were strongly determined by MEH-PPV content and the thin film processing condition. The intensity of PTOA blue emission was equal to that of MEH-PPV orange-red emission when the device was fabricated by a polymer composite film containing 10 wt % of MEH-PPV. Color purity [Commission Internationale de L'Eclairage (CIE x,y ) coordinates (0.26,0.33)] was nearly white emission under applied 8 V. The brightness and current efficiency of PTOA-MEH-PPV composite film based devices increased as MEH-PPV content increased. Furthermore, white emission blue shifted with increasing spin-rate of thin film coating and applied voltage. Low turn-on voltage, high current density, and high brightness were obtained for the device fabricating with light emitting layer coating with high spin-rate. Moreover, low current efficiency was obtained for the PLED with a thinner light-emitting layer. A white emission CIE (0.28,0.34) was obtained for PTOA-MEH-PPV based white PLED. White PLED brightness and efficiency can be as high as 700 cd/m 2 and 0.78 cd/A, respectively.

Combining polymeric architectures with metal ions produces hybrid materials with extremely rich properties. We have been studying polymers containing terpyridine in the side chain. This report discusses a novel white‐light emission from a two‐emitter system comprising a blue‐emitting dysprosium‐chelated polymer and a red‐emitting ruthenium complex. The polymer architecture easily allows the incorporate of blue color into the material and provides a matrix which leads to the facile production of truly white light.
