    摘要: The present invention relates to amorphous thin films and methods of manufacturing the same. These amorphous thin films contain zirconium oxide (ZrO2), preferably at a concentration of at least 30 mol %, and other metal oxides and have surprisingly good mechanical and optical properties. In some embodiments of the present invention, the thin films may be further processed to obtain fluorinated glasses containing the same metal elements as the metal oxides.

    摘要: A process for producing an optical glass product having a predetermined distribution of refractive index in the interior of the product is disclosed. The process comprises the steps of:(a) preparing an aqueous silicate solution containing from about 0.1 to about 0.6 mol/liter of Si (as SiO.sub.2) comprising silicic acid and at least one element selected from the group consisting of rubidium, thallium and cesium;(b) mixing the silicate solution with an acidic aqueous solution, and letting the two solutions react with each other for a period of time sufficient for polymerization to produce a porous gelled product wherein the silica particles are agglomerated;(c) leaching the gelled product with a liquid selected from the group consisting of water, a weakly acidic aqueous solution, an aqueous solution having an alkali metal salt dissolved therein and an aqueous solution of organic matter capable of dissolving Rb.sub.2 O, Cs.sub.2 O, or Tl.sub.2 O, unitl the center of the product starts to dissolve; and(d) drying the leached product in a predetermined atmosphere, and further heating the partially leached gelled product at a temperature sufficiently high to eliminate the particulate material but lower than the melting point of the silica.

    摘要: The invention provides a process of obtaining a gradient index type of optical element with profiles of first and second metal component concentrations by the sol-gel method. The process of fabricating a gradient index type of optical element comprises steps of dipping a silicon component-containing wet gel prepared by the sol-gel method in a solution containing an alkoxide of at least one metal component selected from a first group consisting of Ti, Nb, Ta, and Zr or a derivative thereof to thereby impart to the wet gel a concentration gradient with a concentration of the first metal component decreasing from a periphery to a center of the wet gel, allowing at least one metal component selected from a second group consisting of Ba, La, Y, Gd, Sr, Ca, and Zn to be dissolved out of the wet gel to thereby impart to the wet gel a concentration gradient with a concentration of the second metal component increasing from the periphery to the center of the wet gel, and drying, and firing the wet gel.
