  • a disadvantage of this method is that, based on a particular metal used only a variety of areas can be generated, which is the same Have discoloration, so that only "monochrome" images can be written by means of the known method in glass.
  • the object of the invention is to provide a method by means of which in a simple manner also different colored structures, even when using a doping with only one metal in a glass can be generated.
  • the intensity of the discoloration can be varied.
  • the irradiation time pulse duration or length of CW irradiation
  • irradiation intensity, focus diameter, etc. may be changed to produce different gradations of the same color in different regions of a glass. Accordingly, different optically dense regions of a coloring are produced.
  • the type and / or strength of the induced process is dependent on the initial coloration that was produced in the first method step according to the invention.
  • the further processes taking place in the second step then ensure that the areas which have an initial coloration and which have undergone this second treatment have a different color at the end of the process.
  • various methods may be used for localized energy input of the first step, such as electron beam processes, ion implantation or laser processes.
  • it may be provided in principle that during or before the first step according to the invention, in particular, a local doping of the glass with metal particles takes place.
  • a metal ion donor medium is arranged so that by the energy input of the first method step according to the invention in a first period initially a localized doping of the glass with the metal ions of the donor medium takes place, whereupon in a subsequent period of time Step the discoloration of the ions doped in the glass, if necessary, also the existing ions takes place.
  • this can be done by means of focused laser radiation.
  • doping takes place by diffusion with metal ions, such as silver ions, from a donor medium when the glass is heated in the focal region, in particular below the glass transition temperature. If the glass reaches a higher temperature, in particular above the transformation temperature, then a reduction of the Glass, for example, by the glass-own or externally supplied reducing agent to a conversion of the ions into metal particles, which leads to the said discoloration with the typical color of the metal used.

  • the pattern in the circles itself is not a detail of the picture but should represent a uniform monochrome color.
  • This shift of the absorption maxima or the addition of further absorption maxima at additional wavelengths due to the temperature treatment produces color shifts or blending effects that result in the colors in the present examples of light yellow and green starting from the original color sepia typical of silver , Different colors can be generated when other metals are used in the doping, eg gold, copper etc.

Abstract

L'invention concerne un procédé de production de structures en couleurs dans le verre. Les ions d'au moins un métal présents dans le verre ou introduits par le procédé sont réduits par un apport d'énergie localement délimité, notamment dans le foyer d'un rayonnement laser et transférés dans un amas localement délimité de particules métalliques, ce qui engendre une altération de la couleur locale typique pour le métal utilisé. L'invention est caractérisée en ce que la production de structures multicolores consiste, dans une première étape, à produire plusieurs zones localement délimitées avec une coloration initiale monochrome, ces zones se distinguant par des gradations de la même couleur et, dans une deuxième étape, sont induits des processus de formation de particules et/ou de croissance indépendants par un apport d'énergie global ou local dans les zones de la coloration initiale de telle façon que les zones ayant différentes colorations initiales obtiennent une couleur différente. L'invention concerne également un élément verre présentant une représentation imagée avec des zones de différentes couleurs, produites selon le procédé.
