    Abstract: Gegenstand dieser Erfindung ist es, eine lichtemittierende Vorrichtung der nächsten Generation von optischen Vorrichtungen zu schaffen, die eine breite Emissionseigenschaft besitzt, bei der die Breite bei einem halben Maximum eines Emissionsspektrums in einem Wellenlängenbereich von sichtbarem Licht groß ist und die Fähigkeit vorhanden ist, eine Weißlichtemittierung durch Fotolumineszenz (PL) zu beobachten.
    Bei einem Ausbackverfahren für die Aushärtung einer Formpressung, die durch Formpressung von feinen Silikatpartikeln, wie begasten Silikaten, bei einer Ausbacktemperatur von nicht höher als 1000° C entsteht, werden Hydroxylgruppen der feinen Silikatpartikel in ausreichendem Maße einer Entwässerungskondensationsreaktion ausgesetzt, so dass die Partikel transparent werden. Bei dem Verfahren entwickelt sich eine Störstellenstruktur, die ohne Entspannung aufrechterhalten bleibt, wodurch ein Quarzglas erzeugt wird. Das Quarzglas wird als Leuchtstoff verwendet

    Abstract: A process produces a glass overcladding tube from a silica gel body. The process includes passing the gel body through a hot zone under conditions that cause partial sintering of the gel body and repassing the gel body through the hot zone under conditions that further sinter the gel body into a glass overcladding tube. A preform for an optical fibre, comprising core, cladding layer and overcladding tube is also disclosed; the overcladding tube being the sintered, sol-gel produced, silica tube obtainable by the disclosed and claimed process of sintering the silica gel body.

    Abstract: The invention relates to a crucible characterized in that said crucible is of high purity and high opacity or exhibits low transmission characteristics in the IR range and is derived from a quartz glass crucible known in prior art. Said crucible known in prior art has a crucible body which is symmetrical about a rotational axis and said body is made of opaque quartz glass, whereby the crucible has an outer zone (3) made of opaque quartz glass which projects radially inwards to an inner zone (2) made of transparent quartz glass having a density of at least 2.15 g/cm3. The crucible body (1) is made of a synthetic SiO¿2? granulate with a specific surface (according to BET) in the range of 0.5 m?2¿/g to 40 m2/g and having a stamp density of at least 0.8 g/cm3 and is produced from an at least partially porous agglomerate of SiO¿2? primary particles. A method for producing said quartz glass crucible is characterized according to the invention in that during the production of said crucible, an at least partially porous agglomorate of synthetically produced SiO2 granulate made of SiO2 primary particles is produced having a specific surface (according to BET) in the range of 0.5 m?2¿/g to 40 m2/g and a stamp density of at least 0.8 g/cm3. Heating is performed in such a manner that a vitrification front progresses from the inside to the outside of an inner zone (4) made of transparent quartz glass.
