Patent number: 11534754Abstract: A method for producing a cavity in a substrate composed of hard brittle material is provided. A laser beam of an ultrashort pulse laser is directed a side surface of the substrate and is concentrated by a focusing optical unit to form an elongated focus in the substrate. Incident energy of the laser beam produces a filament-shaped flaw in a volume of the substrate. The filament-shaped flaw extends into the volume to a predetermined depth and does not pass through the substrate. To produce the filament-shaped flaw, the ultrashort pulse laser radiates in a pulse or a pulse packet having at least two successive laser pulses. After at least two filament-shaped flaws are introduced, the substrate is exposed to an etching medium which removes material of the substrate and widens the at least two filament-shaped flaws to form filaments. At least two filaments are connected to form a cavity.Type: GrantFiled: April 26, 2019Date of Patent: December 27, 2022Assignee: Schott AGInventors: Andreas Ortner, Andreas Roters, Hauke Esemann, Markus Heiss-Chouquet, Fabian Wagner, Laura Brueckbauer, Stephanie Mangold, Vanessa Hiller

Publication number: 20210344039Abstract: The disclosure relates to an aluminum-doped lithium ion conductor based on a garnet structure comprising lanthanum, in particular an aluminum-doped lithium lanthanum zirconate (LLZO), in which the latter is co-doped with at least one trivalent M3+ ion on the lanthanum site, and in which the trivalent M3+ ion has an ionic radius that is smaller than that of La3+, and a higher lithium content is present in comparison to a stoichiometric garnet structure, with the provision that if M3+ is yttrium, a further trivalent M3+ ion, which is different than Y3+ and has an ionic radius that is smaller than that of La3+, is co-doped on the lanthanum site. A co-doping strategy is carried out, in which a doping on the lanthanum site with ions of the same valence, but smaller diameter brings about the change in the lattice geometry to the cubic modification. This leads to a stabilization of the cubic crystal modification that is present also with superstoichiometric quantities of lithium.Type: ApplicationFiled: April 29, 2021Publication date: November 4, 2021Applicant: SCHOTT AGInventors: Sebastian Leukel, Meike Schneider, Andreas Roters, Jörg Schumacher, Wolfgang Schmidbauer, Bernd Rüdinger
