    摘要: Durable and scratch resistant articles including low-reflectance optical coating with gradient portion. In some embodiments, an article comprises: a substrate comprising a first major surface; and an optical coating disposed over the first major surface. The optical coating comprises: a second major surface; a thickness; and a first gradient portion. A refractive index of the optical coating varies along a thickness of the optical coating. The difference between the maximum refractive index of the first gradient portion and the minimum refractive index of the first gradient portion is 0.05 or greater. The absolute value of the slope of the refractive index of the first gradient portion is 0.1/nm or less everywhere along the thickness of the first gradient portion. The article exhibits a single side photopic average light reflectance of 3% or less, and a maximum hardness from 10 GPa to 30 GPa.

    摘要: A method of making a device substrate article having a device modified substrate supported on a glass carrier substrate, including: treating at least a portion of the first surface of a device substrate, at least a portion of a first surface of a glass carrier, or a combination thereof, wherein the treating produces a surface having: silicon; oxygen; carbon; and fluorine amounts; and a metal to fluorine ratio as defined herein; contacting the treated surface with an untreated or like-treated counterpart device substrate or glass carrier substrate to form a laminate comprised of the device substrate bonded to the glass carrier substrate; modifying at least a portion of the non-bonded second surface of the device substrate of the laminate with at least one device surface modification treatment; and separating the device substrate having the device modified second surface from the glass carrier substrate.

    摘要: A method of fabricating a liquid lens or an array of liquid lenses, and the corresponding liquid lens or array of lenses is disclosed. The method includes patterning an insulative layer (132) by photolithographic techniques to expose a portion of the conductive layer (124) and a portion of the insulative layer (132) having a surface energy below 40 mJ/m2. In further embodiments, the liquid lens includes an interface (110) forming a lens between a polar liquid (106) and a non-polar liquid (108) disposed within a cavity (104). The interface intersects a surface of the insulative layer (132) having a surface energy below 40 mJ/m2.
