When the two are joined, ions diffuse across. Located in media Etched nanostructured rings around an LED can make it more than seven times brighter. The novel technique developed at NIST may have applications in areas such as in biomedical imaging where LED brightness is crucial. Located in media The principle architecture of a bottom emission OLED incorporating the intrinsic emission layers into the Novaled PIN OLED® technology by using doped transport layers: holes are injected from the anode and transported by p-hole transport layer (p-HTL) to the emitting layer (EML). Electrons are injected from the cathode and transported by the n-electron transport layer (n-ETL). Recombination of the charge carriers takes place in the EML and light is emitted Located in media Large-scale prototype of the transparent white OLED tile. Located in media Optical image of the same nanowire in action. Most of the light emitted from the device is in the ultraviolet portion of the spectrum, but enough visible light is generated to see it glowing. Located in media Micrograph of a complete nanowire LED. The long nanowire (A) is about 110 micrometers long, a shorter nanowire (B) crosses it. The circular section is the metal post from which the nanowires are aligned.

Located in media In a device such as an optical display, positive (purple) and negative (gold) charges are attracted strongly to one another and become trapped (first picture). Because of the unusual rules of quantum physics, the trapped charges can emit light (second picture) if they are spinning in opposite directions. Van Voorhis is creating simulations to show how to selectively create trapped charges in organic light-emitting diode displays to improve efficiency.

The computer plots show how energy intensity (ranging from low in blue to high in red) varies as electronic structures called excitons absorb laser light and emit energy at various frequencies. The pair of similar "butterflies" indicates that an exciton is absorbing and emitting energy in a predictable pattern.
