ALKALINE EARTH METAL SILICATE LUMINOPHORE AND METHOD FOR IMPROVING THE LONG-TERM STABILITY OF AN ALKALINE EARTH METAL SILICATE LUMINOPHORE
xyzz with x, y, z > 0. The component EA is formed by one or more alkaline earth metals. An activator is doped into the basic grid. In a step of the method, the grains of the luminophore are heated in a reactor chamber (01). A volatile organoaluminum compound is heated and flowed through with a first carrier gas, as a result of which a first carrier gas mixture containing the volatile organoaluminum compound is obtained. In addition, water is heated and a second carrier gas flows through, as a result of which a second carrier gas mixture containing the water is obtained. The first carrier gas mixture and the second carrier gas mixture are introduced into the reactor chamber (01) where the grains of the alkaline earth metal silicate luminophore are enveloped by the carrier gas mixtures. As a result, the volatile organoaluminum compound and the water react with one another at least predominantly to form aluminum oxide hydroxide which forms a coating of the grains of the alkaline earth metal silicate luminophor. The invention further relates to an alkaline earth metal silicate luminophore.

Zinc sulphide phosphor having photo- and electroluminescent properties, process for producing same, and security document, security feature and method for detecting same
The present invention relates to a zinc sulphide phosphor and to a process for producing same. The invention further relates to a security document or document of value, to a security feature and to a method for detecting same. The phosphor according to the invention can act as electroluminescent phosphor and thus be excited by an electrical field, and this can result in emission of electroluminescent light in the blue and/or green color region of the visible spectrum. The phosphor can moreover be excited by UV radiation in the wavelength range than 345 nm to 370 nm, and can thus emit photoluminescent light in the blue color region of the visible spectrum. The phosphor can moreover be excited by UV radiation in the wavelength range from 310 nm in 335 nm, and can thus emit photoluminescent light in the green color region of the visible spectrum.

The invention relates to a luminescent substance consisting of a doped host lattice which absorbs at least one part of exciting radiation whet it is excited by a high-energy exciting radiation, thereby releasing an energy-poor emission radiation. According to said invention the host lattice is embodied in the form of a carbidonitridosilicate-based compound. An illuminant which is used for producing white light and comprises a light emitting element and said luminescent substance are also disclosed.

CERIA BASED GLASS POLISHING COMPOSITION AND A PROCESS FOR THE MANUFACTURE THEREOF
The invention is directed to a process for the manufacture of a ceria based polishing composition, comprising (a) suspending an inorganic cerium salt or cerium hydroxide with a cerium content calculated as cerium oxide in the range of 50%-100% based on Total rare earth oxide (TREO) in an aqueous medium thereby obtaining an aqueous suspension, (b) treating said aqueous suspension with an acid or a salt of an acid selected from the group of HF, H3PO4 and H2SO4, thereby obtaining a solid suspended in said aqueous medium, (c) separating said solid from said aqueous medium, and (d) calcining the separated solid at a temperature between 750°C and 1,2000C and grinding the calcined solid to grain sizes in the range of 0.5 騜m to 5.0 騜m.
The invention relates to a luminescent material, particularly for use in security documents, comprised of a host lattice made of rare-earth oxysulfide, which is doped with at least two types of ions. The luminescent material exhibits anti-Stokes luminescence according to Stokes' law when it is irradiated with an excitation radiation. According to the invention, the luminescent material contains two luminescent material constituents, which are co-doped with ytterbium/holmium on the one hand and with ytterbium/erbium on the other. The luminescent material can preferably be used for forming security features.

The claimed metal hydride reservoir in the form of a pressure vessel (1) has at least one gas pipe (7) for supplying or discharging gaseous hydrogen and at least one inner container (2) which is arranged in its inner chamber (3) and contains a hydrogen storage material. The metal hydride reservoir is characterised in that at least one inner container (2) comprises two parts interconnected by a gas-permeable filtering medium in such a way that hydrogen but not the hydrogen storage material can flow from the inner container into the inner chamber of the metal hydride reservoir and vice-versa.

Abrégé
The invention relates to solid particles (10) from a and to a method for the production thereof from a flowable starting material (2) and a solid part, wherein the flowable starting material (2) is splitted into droplets (9) which are introduced along a trajectory (50) into a solidification liquid (11) in which they are solidified in the form of the solid particles (10). Said invention is characterised in that the solidification liquid (11) is used and, if the flowable starting material (2) contains actinide oxide, said solidification liquid steadily flows, thereby making it possible to produce solid particles having a greater sphericity and a narrow particle sized distribution.

Removal of arsenic from drinking and process water
A method of removing arsenic and heavy metals from water using metal salt hydroxidegels is provided. The arsenic present in water is adsorbed onto the hydroxide-gels which can effectively be filtered through a diatomaceous earth (DE) filtration bed. The combination of DE mixed hydroxide-gels is also effective in removing arsenic from water and heavy metals from water.
