摘要： Gegenstand der Erfindung ist eine auf der Nanotechnologie basierende lichtempfindliche Beschichtung mit der Eigenschaft, in einem reversiblen Prozess, allein unter Lichteinwirkung, ohne thermische Behandlung, die Farbe zu wechseln.
Im Unterschied zu bekannten lichtempfindlichen Glasuren verbessert der eingebrannte Nanoglasurversatz die optischen Eigenschaften und reversiblen Prozesse im Glasurraum. Die Abbildungsqualität, die Schärfe und der Kontrast der Lichtbilder werden signifikant verbessert und die Reaktionsfähigkeit der Beschichtung mit Licht massgeblich erhöht. Es ermöglicht das präzisere Erzeugen von temporären Licht- und Schattenbildern. Zusätzlich gibt es viele Kombinationen mit temporären und fixierten Bildern auf einem Träger.
Dies eröffnet Möglichkeiten in Architektur und Kunst, in der Verwendung als Wand- oder Bodenplatte, in einem Schwimmbad, an einem Brunnen oder als Bank, Tisch, Stuhl oder Möbel und Geschirr und öffnet das Feld für Interaktionen des Menschen mit dem Material und seiner Umgebung.

摘要： A method of producing a polarizing glass article that exhibits a broad band of high contrast polarizing properties in the infrared region of the radiation spectrum, that is phase-separated or exhibits photochromic properties based on silver, copper, or copper-cadmium halide crystals or a combination thereof precipitated in the glass and having a size in the range of 200-5000 Angströms, and that has a surface layer containing elongated silver, copper, or copper cadmium metal particles, or a mixture of same, the method comprising the step of thermally forming and precipitating large halide crystals by subjecting the glass article to a time-temperature cycle in which the temperature is at least 75 °C above the glass softening point. The figure is a graphical representation of stress levels in psi versus center wavelengths (CWLs) in nm, where center wavelength is defined as the center of a given range of polarizing capability. Specifically, the stess levels required to achieve a given center wavelength is compared for two heat treatment cycles. The upper line (A) represents data for the standard heat treatment of polarizing glasses; 710 °C for 4 hours. Line (B) represents data for the new high temperature heat treatment of 750 °C for 8 hours.

摘要： This invention is directed to the preparation of glass articles exhibiting a relatively broad band of high contrast polarizing properties in the infrared region of the radiation spectrum from glasses containing silver halide particles selected from the group consisting of AgCl, AgBr, and AgI. The inventive method comprises the following five general steps:

(a) melting a batch for a glass containing silver and at least one halide selected from the group consisting of chloride, bromide, and iodide;
(b) cooling and shaping said melt into a glass article of a desired configuration;
(c) subjecting said glass article to a temperature at least above the strain point, but not in excess of 75°C above the softening point of the glass, for a sufficient length of time to cause the generation of silver halide particles therein selected from the group consisting of AgCl, AgBr, and AgI, said particles ranging in size between about 200-5000Å;
(d) elongating said glass article under stress at a temperature above the annealing point, but below that where said glass exhibits a viscosity of about 10⁸ poises, such that said silver halide particles are elongated to an aspect ratio of at least 5:1 and aligned in the direction of the stress; and, thereafter,
(e) exposing said elongated glass article to a reducing environment at a pressure greater than atmospheric pressure and at a temperature above about 250°C, but no higher than about 25°C above the annealing point of the glass, for a period of time sufficient to develop a reducing surface layer on said glass article having a thickness of at least 10 microns wherein at least a portion of said elongated silver halide particles are reduced to elemental silver particles having aspect ratios greater than 2:1 which are deposited in and/or upon said elongated particles.

The single figure illustrates the improved contrast and bandwidth achieved by the process (curves B, C and D).
