Welding Nanowires With Light

Electrically conductive meshes made of metal nanowires promise exceptional electrical throughput, low cost, and easy processing in applications like video displays, LEDs, and thin-film solar cells. However, in processing, these meshes must be heated or pressed to unite the crisscross pattern of nanowires that form the mesh - damaging them in the process.

Quantum Dot Light Enhancement Substrate

A cost-competitive solution for increasing the light extraction efficiency of organic light-emitting diodes (OLEDs) with efficient and stable color rendering index (CRI) for solid-state lighting (SSL) was developed and demonstrated. Solution-processable quantum dot (QD) films were integrated into OLED indium tin oxide (ITO)-glass substrates to generate tunable white emission from blue-emitting OLED devices.

Fully Printed Carbon Nanotube Transistor Circuits for Displays

Organic light-emitting diode (OLED)-based displays are used in cell phones, digital cameras, and other portable devices. But developing a lower-cost method for mass-producing such displays has been complicated by the difficulties of incorporating thin-film transistors that use amorphous silicon and polysilicon into the production process.
