Photoluminescent nanofiber composites, methods for fabrication, and related lighting devices

Title: Photoluminescent nanofiber composites, methods for fabrication, and related lighting devices

A photoluminescent nanofiber composite includes a nanofiber substrate, first luminescent particles, and second luminescent particles. The first luminescent particles are supported by the nanofibers and span at least a portion of a substrate surface, as a layer on the substrate surface, or with some particles located in a bulk of the substrate, or both. The second luminescent particles are disposed on the substrate. The second luminescent particles may be disposed directly on the substrate surface or on the first luminescent particles. The second luminescent particles may be deposited in a pattern of deposition units. The first and second luminescent particles are configured for emitting light of different respective wavelengths in response to excitation by a light beam. One or more surface treatment coatings may be provided at different locations.

Three-dimensional stacked structured ASIC devices and methods of fabrication thereof

Patent Shinde, Subhash L. ; Teifel, John ; Flores, Richard S. ; Jarecki Jr., Robert L. ; Bauer, Todd

A 3D stacked sASIC is provided that includes a plurality of 2D reconfigurable structured structured ASIC (sASIC) levels interconnected through hard-wired arrays of 3D vias. The 2D sASIC levels may contain logic, memory, analog functions, and device input/output pad circuitry. During fabrication, these 2D sASIC levels are stacked on top of each other and fused together with 3D metal vias. Such 3D vias may be fabricated as through-silicon vias (TSVs). They may connect to the back-side of the 2D sASIC level, or they may be connected to top metal pads on the front-side of the 2D sASIC level.

Photonic devices on planar and curved substrates and methods for fabrication thereof

Patent Bartl, Michael H. ; Barhoum, Moussa ; Riassetto, David

A versatile and rapid sol-gel technique for the fabrication of high quality one-dimensional photonic bandgap materials. For example, silica/titania multi-layer materials may be fabricated by a sol-gel chemistry route combined with dip-coating onto planar or curved substrate. A shock-cooling step immediately following the thin film heat-treatment process is introduced. This step was found important in the prevention of film crack formation--especially in silica/titania alternating stack materials with a high number of layers. The versatility of this sol-gel method is demonstrated by the fabrication of various Bragg stack-type materials with fine-tuned optical properties by tailoring the number and sequence of alternatingmore »« less
