Rear earth aluminoborosilicate glass composition

Номер: US20120033693A1
Автор: Carsten Weinhold, Hong Li
Принадлежит: Schott North America Inc

The invention relates to aluminoborosilicate-based glasses suitable for use as a solid laser medium. In particular, these aluminoborosilicate-based laser glasses exhibit broad emission bandwidths of rare earth lasing ions. Although not entirely understood, the broadening of the emission bandwidth is believed to be achieved by the presence of significant amounts of lanthanide ions in the glass matrix. In addition, because of the high values of Young's modulus, fracture toughness and hardness, the rare earth aluminoborosilicate glass system according to the invention is also suitable as transparent armor window material.

Принадлежит: Shin Etsu Chemical Co Ltd

A titania-doped quartz glass suited as an EUV lithographic member is prepared by feeding a silicon-providing reactant gas and a titanium-providing reactant gas through a burner along with hydrogen and oxygen, subjecting the reactant gases to oxidation or flame hydrolysis to form synthetic silica-titania fine particles, depositing the particles on a rotating target, and concurrently melting and vitrifying the deposited particles to grow an ingot of titania-doped quartz glass. The target is retracted such that the growth front of the ingot may be spaced a distance of at least 250 mm from the burner tip.

Автор: Adam James Ellison, George Halsey Beall, Glenn Eric Kohnke, Ivan A. Cornejo, Lisa Ann Lamberson
Принадлежит: Corning Inc

Opal glass compositions and devices incorporating opal glass compositions are described herein. The compositions solve problems associated with the use of opal glasses as light-scattering layers in electroluminescent devices, such as organic light-emitting diodes. In particular, embodiments solve the problem of high light absorption within the opal glass layer as well as the problem of an insufficiently high refractive index that results in poor light collection by the layer. Particular devices comprise light-emitting diodes incorporating light scattering layers formed of high-index opal glasses of high light scattering power that exhibit minimal light attenuation through light absorption within the matrix phases of the glasses.

The result is a metallic electrically conductive via between the collector lines on the front side and the emitter electrode on the back-side of the solar cell. The paste can also be used to form the collector lines on the front-side of the solar cell and the emitter electrode on the back-side of the solar cell. Also disclosed are metal-wrap-through silicon solar cells comprising the fired conductive silver paste.
