Abstract:
The invention relates to reflective features formed from multiple inks. In one embodiment, the reflective feature includes a substrate having a first region and a second region, the first and second regions having different surface characteristics; a first reflective element disposed on the first region; and a second reflective element disposed on the second region, wherein the first reflective element is more adherent than the second reflective element to the first region. In another embodiment, the reflective feature includes multiple layers formed from different inks exhibiting enhanced reflectivity and/or durability. The invention is also to processes for forming these features, preferably through a direct write printing process.
Abstract:
A precursor composition for the deposition and formation of an electrical feature such as a conductive feature. The precursor composition advantageously has a low viscosity enabling deposition using direct-write tools. The precursor composition also has a low conversion temperature, enabling the deposition and conversion to an electrical feature on low temperature substrates. A particularly preferred precursor composition includes silver metal for the formation of highly conductive silver features.

Abstract:
Precursor compositions for the deposition of electronic features such as resistors and dielectric components and methods for the deposition of the precursor compositions. The precursor compositions have a low viscosity, such as not greater than about 1000 centipoise and can be deposited using a direct-write tool. The precursors also have a low conversion temperature, enabling the formation of electronic features on a wide variety of substrates, including low temperature substrates.

Reflective electronic layers are provided for electronic devices, such as electroluminescent lamps, photovoltaic devices, and light emitting diodes. Processes for forming such reflective layers are also provided. The reflective layers comprise metallic particles that optionally are coated.
Abstract:
Provided are silver-containing powders and a method and apparatus for manufacturing the silver-containing particles of high quality, of a small size and narrow size distribution. An aerosol is generated from liquid feed and sent to a furnace, where liquid in droplets in the aerosol is vaporized to permit formation of the desired particles, which are then collected in a particle collector. The aerosol generation involves preparation of a high quality aerosol, with a narrow droplet size distribution, with close control over droplet size and with a high droplet loading suitable for commercial applications.
Abstract:
This invention is directed to direct write printed reflective features comprising metallic particles and/or metallic nanoparticles. Preferably, the reflective feature are formed by a direct-writing printing process, e.g., a piezo-electric, thermal, drop-on-demand or continuous ink jet printing process, using an ink comprising metallic particles, e.g., metallic nanoparticles. The invention is also directed to inks suitable for printing such reflective features using a direct write printing process and to processes for making such reflective features.
