Publication number: 20220397719Abstract: An article includes an optical transforming layer and a guide region positioned inside and adjacent to at least a portion of a perimeter of the optical transforming layer. The guide region comprises an inlet end positioned adjacent to a first surface of the optical transforming layer and an outlet end positioned adjacent a second surface of the optical transforming layer. The guide region propagates light from the inlet end to the outlet end such that the light is directed from the first surface to the second surface. The guide region includes a phase-separated glass comprising a continuous network phase and a discontinuous phase. A relative difference in index of refraction between the continuous network phase and the discontinuous phase is greater than or equal to 0.3%. The discontinuous phase comprises elongated shaped regions aligned along a common axis and having an aspect ratio greater than or equal to 10:1.Type: ApplicationFiled: June 7, 2022Publication date: December 15, 2022Inventors: Nicholas Francis Borrelli, Ming-Jun Li, Xiao Li, David John McEnroe, Robert Adam Modavis, Daniel Aloysius Nolan, Alranzo Boh Ruffin, Vitor Marino Schneider, Thomas Philip Seward, III, Alexander Mikhailovich Streltsov

Patent number: 10683232Abstract: A photochromic glass that includes a base glass and a photochromic agent is described. The base glass is a modified boroaluminosilicate glass and the photochromic agent is a nanocrystalline cuprous halide phase. The photochromic glass exhibits a sharp cutoff in the UV or short wavelength visible portion of the spectrum along with an absorption band at longer wavelengths in the visible. The nanocrystalline cuprous halide phase includes Cu2+, which provides states within the bandgap of the cuprous halide that permit the glass to absorb visible light. Absorption of visible light drives a photochromic transition without compromising the sharp cutoff. The nanocrystalline cuprous halide phase may optionally include Ag.Type: GrantFiled: September 5, 2018Date of Patent: June 16, 2020Assignee: Corning IncorporatedInventors: Roger Jerome Araujo, Nicholas Francis Borrelli, Nadja Teresia Lönnroth, David Lathrop Morse, Thomas Philip Seward, III

Publication number: 20090011925Abstract: A catalytically active glass-ceramic and method for producing a catalytically active multi-phase glass-ceramic in which at least one catalyst precursor is mixed with a glass-ceramic precursor formulation to form a catalyst precursor/glass-ceramic precursor mixture. The catalyst precursor/glass-ceramic precursor mixture is then melted to form an amorphous glass material which, in turn, is devitrified to form a polycrystalline ceramic. The polycrystalline ceramic is then activated, forming a catalytically active multi-phase glass-ceramic.Type: ApplicationFiled: July 6, 2007Publication date: January 8, 2009Inventors: Larry Gordon Felix, David Morrissey Rue, Thomas Philip Seward, III, Logan Edwin Weast

Patent number: 4086089Abstract: The present invention is directed to a method for producing patterned color-triad arrays in glass for use in color television picture tubes, such arrays being capable of acting as spectrally-selective filters and to provide the desired color information when the television tube is operating. The color-triad arrays are produced by sequentially or simultaneously exposing a polychromatic glass through an electron shadow mask to high energy or actinic radiation and thereafter following the heat treatment and re-exposure practice known to develop colors within polychromatic glass. The filtering action provided by the color triads integrally present within the glass can enhance the contrast of the color image produced. Also, the presence of the color triads in the glass permits the use of a single "white" phosphor, rather than a red, a green and a blue phosphor as are presently used in the conventional color television picture tube.Type: GrantFiled: March 17, 1977Date of Patent: April 25, 1978Assignee: Corning Glass WorksInventors: Thomas Philip Seward, III, Brent Merle Wedding
