The illumination of azobenzene molecules with UV/visible light efficiently converts the
molecules between trans and cis isomerization states. Isomerization is accompanied by a …

Progress in understanding the major loss mechanisms have led to rapid improvements in
efficiency that have meant that OLEDs will soon be the material of choice for many display …

The first advanced textbook to provide a useful introduction in a brief, coherent and
comprehensive way, with a focus on the fundamentals. After having read this book, students …

We demonstrate that ordered microlens arrays with 10 μm diam poly-dimethyl-siloxane
lenses attached to glass substrates increase the light output of organic light emitting devices …

Since the advent of quantum mechanics and the clear demonstration of the existence
of'matter waves', physicists have never failed to take advantage of concepts and theoretical …

In almost all areas of daily life the demands on the communications infrastructure increased
dramatically. With regard to the volume of data that has to be transmitted, no matter whether …

A truncated-inverted-pyramid (TIP) chip geometry provides substantial improvement in light
extraction efficiency over conventional AlGaInP/GaP chips of the same active junction area …

Electromagnetic band structure can produce either an enhancement or a suppression of
spontaneous emission from two-dimensional (2-D) photonic crystal thin films. We believe …

We describe a promising thin-slab light-emitting diode LED design, which uses a highly
efficient coherent external scattering of trapped light by a two-dimensional 2D photonic …

Surface plasmons limit the efficiency of organic light‐emitting diodes (OLEDs). Up to 40% of
the radiative power may be lost to surface plasmon (SP) modes associated with the metallic …
