摘要:A process is disclosed for the production of persistent phosphors, comprising exposing particles of phosphor precursors for a short time to a heat source selected from a particle plasma and an open flame arising from the combustion of hydrocarbons. A process for coating a substrate with persistent phosphors is also disclosed, comprising directing a stream of phosphor precursor particles for a short time through the same types of heat source toward the substrate. Preferred phosphors are Strontium Aluminate-based doped with Dysprosium and Europium.

摘要:Synthesis gas is produced according to this invention using a combination of steam reforming and oxidation chemistry. The process incorporates the use of solids to heat the hydrocarbon feed, and to cool the gas product. According to the invention, heat can be conserved by directionally reversing the flow of feed and product gases at intermittent intervals.

摘要:The present invention relates to long decay phosphors comprising rare earth activated strontium aluminates and methods for producing them. The phosphors comprise a matrix of the formula Sr 4 Al 14 O 25 comprising europium as an activator and a further rare earth element as a co-activator, wherein the molar ratio of Al/Sr in the starting materials is in the range of 3.1 to less than 3.5 and the ratio of Eu/Sr is in the range of 0.0015 to 0.01. The process for the preparation of a phosphor comprises the steps of milling the starting materials for the synthesis of the phosphor, the starting materials comprising a boron compound selected from boric acid, boric oxide or a borate salt in an amount such that the B/Sr molar ratio is between 0.1 and to 0.3, treating the milled composition with heat, grinding the block material which is obtained through the heat treatment, ball-milling the crushed material, sieving the material, and washing the material with an aqueous solution.
