Definitions

  • the invention relates to an attachment for screens or the like, such as cathode ray tubes of monitors, television sets or the like, with a glass pane which has a multilayer anti-reflection coating on its front facing away from the screen or the like and, if appropriate, a reflection-reducing, in particular on its rear facing the screen or the like has an absorbent coating (or the like).
  • screens or the like such as cathode ray tubes of monitors, television sets or the like
  • a glass pane which has a multilayer anti-reflection coating on its front facing away from the screen or the like and, if appropriate, a reflection-reducing, in particular on its rear facing the screen or the like has an absorbent coating (or the like).
  • the coating used for such attachment units should have a low surface resistance in order to be able to shield electromagnetic radiation. This usually requires an electrical sheet resistance of less than 100 ohms.
  • Double-layer systems for front-end units of the type mentioned at the outset, with which a good anti-reflective effect could be achieved over wide areas of the visible spectrum, are not known, rather the use of such simple layer systems is always associated with an intense color impression. Multi-layer systems are therefore used to reduce the color cast, but these require a much higher production expenditure.
  • the glass pane which there as well as in the invention can consist either of inorganic glass, in particular of tempered safety glass, or also of plastic, ie organic glass, has an absorption coating made of, for example, chrome on the back and an anti-reflection coating made of two or three layers with a different refractive index on the front, with the neutrality of the color impression and the manufacturing effort leave a wish.
  • an anti-reflection coating for glass panes in which a successive metal layer made of a material with a high degree of reflection but low absorption and a dielectric interference layer made of SiO2, for example, are applied to the glass panes, with copper, Silver, rhodium, aluminum or other similarly stable metals with the aforementioned properties are specified.
  • the use of such an antireflection coating in front-mounted units of the generic type leads, if metals other than copper are selected, to an undesirably intense color impression, while the use of copper is prohibited because of its lack of resistance for front-side coatings of front-mounted units of the type in question here.
  • GB-PS 826 754 electrically conductive coatings are described on glass panes, which can alternatively contain a gold, silver, nickel or iron layer as well as part of an outer anti-reflective layer, for example SiO2, with the exception of the use of gold intense color impression can be accepted in the field of application specified there and no indication is given to produce a neutral color impression by appropriate choice of material for the metal layer.
  • an outer anti-reflective layer for example SiO2
  • DE-PS 21 38 517 relates to a heat shield with a coating of gold and high-index dielectric material, the use of such a coating would not allow the desired reflection reduction in an attachment of the generic type.
  • the invention has for its object to provide a front unit of the generic type, the anti-reflective coating allows economical reduction of the light reflectance of the front of the glass pane from about 4% to less than 0.5%, is largely neutral in color and has a sheet resistance of less with economical production than 100 ohms.
  • the antireflection coating comprises a metal layer made of gold or a metal alloy with a gold content of more than 50% with a thickness of 4 to 10 nm and an essentially absorption-free layer on the side facing away from the glass pane, as an anti-reflective layer for has the visible spectral range interference layer made of dielectric material with a refractive index of n ⁇ 1.8.
  • the thickness of the metal layer is 5 to 7 nm.
  • the invention further proposes that the optical thickness of the interference layer is 60 to 140 nm.
  • the interference layer consists of at least one metal or semimetal oxide.
  • the interference layer consists of SiO2.
  • Another embodiment of the invention is characterized in that between the glass pane and the metal layer and / or an adhesive layer is arranged between the metal layer and the interference layer (in each case).
  • NiCr, silicon, indium oxide and / or indium tin oxide is used as the material for the adhesive layer (s).
  • the invention also proposes that at least some of the layers of the anti-reflective coating be produced by magnetron sputtering.
  • the invention is based on the surprising finding that the interaction of the metal and the interference layer according to the invention can achieve an antireflective color-neutral effect for a double-layer system. Hence, this effect is due to the unusual course of gold's complex refractive index, which is distinguished by the fact that its real part falls monotonously significantly in the visible spectrum.
  • DE-PS 21 38 517 describes the use of gold in conjunction with a high-refractive antireflection coating, while the object on which the invention is based can only be achieved by a combination of the gold layer and the low-refractive interference layer in the sense of the claimed antireflection coating is.
  • the glass pane 10 again consists of a float glass pane made of soda-lime-silicate glass with a thickness of 4 mm
  • a NiCr adhesive layer 16 with a thickness of 0.5 nm is successively applied to the glass pane 10
  • a gold layer 12 with a thickness of 6 nm is successively applied to the glass pane 10
  • attachment unit according to FIG. 2 was manufactured as follows:
  • the adhesive layer 16 as NiCr adhesive layer of 0.5 nm thickness by sputtering a NiCr (80/20) target in an argon atmosphere at a pressure of 1.5 ⁇ 10 ⁇ 1 Pa
  • the gold layer 12 of 6 nm thickness by sputtering a gold target in argon Atmosphere at a pressure of 1.5 ⁇ 10 ⁇ 1 Pa
  • the adhesive layer 18 as a SnO2-doped In2O3 adhesive layer in a thickness of 4 nm by reactive sputtering of the In90 / Sn10 target in an argon-oxygen atmosphere at a pressure of 3.5 ⁇ 10 ⁇ 1 Pa
  • the interference layer 14 as a SiO2 layer of 60 nm thickness by reactive sp
  • Fig. 4 shows that the real part of the complex refractive index of gold drops significantly monotonically over the visible spectral region, whereupon the surprising effect of the attachment unit according to the invention, in combination with the low-refractive interference layer used, may be essentially attributable.
