    摘要: A light-emitting device includes a substrate that is at least partially transparent to optical radiation and has a first index of refraction. A diode region is disposed on a first surface of the substrate and is configured to emit light responsive to a voltage applied thereto. An encapsulation layer may be disposed on a second surface of the substrate and has a second index of refraction. An antireflective layer stack is formed within the substrate directly below the second surface of the substrate. The antireflective layer has an amorphous non-porous first layer, a porous second layer, an optional amorphous non porous third layer, and a fourth layer with modified crystallinity. The encapsulation layer may also be omitted and the substrate's second surface may separate the substrate, which has an antireflective layer stack within the substrate, directly below the second substrate surface, from air.

    摘要: The invention concerns a process for increasing the scratch resistance of a glass substrate by implantation of simple charge and multicharge ions, comprising maintaining the temperature of the area of the glass substrate being treated at a temperature that is less than or equal to the glass transition temperature of the glass substrate, selecting the ions to be implanted among the ions of Ar, He, and N, setting the acceleration voltage for the extraction of the ions at a value comprised between 5 kV and 200 kV and setting the ion dosage at a value comprised between 1014 ions/cm2 and 2.5×1017 ions/cm2.The invention further concerns glass substrates comprising an area treated by implantation of simple charge and multicharge ions according to this process and their use for reducing the probability of scratching on the glass substrate upon mechanical contact.

    摘要: A solar energy reflector (1) comprises a mirror (5) with no copper layer laminated to a supporting sheet (7) by means of a bonding material (6). The edges of the mirror (5) are provided, at least on a portion forming the major part of their height and closest to the metallic sheet, with an edge protection (8) made of a material comprising silicone, polyurethane and/or acrylic and the material forming the edge protection (8) is different from the bonding material (6).
