| 20110043099 | ABOS:M-BASED PHOSPHORS AND LIGHT SOURCES CONTAINING THESE PHOSPHORS - This invention is related to efficient anorganic phosphors, which are based on an oxysulfide host lattice of the general formula ABOS: M. Furthermore, this invention is related to the use of these phosphors in various technical applications such as fluorescent lamps, colored light or white light emitting LEDs, scanning beam displays working with UV or purple laser as exciting source and other devices in order to convert especially UV or NUV radiation or short-wave visible light into an useful longer-wave visible radiation. This invention is also related to light sources and/or display applications that contain the inventive phosphor. An inventive phosphor shows the general formula ABOS: M, where A is at least one element selected from the group consisting of Ca, Mg, Sr, and Ba; B is at least one element selected from the group consisting of Zn and Mg; M is at least one first element selected from the group consisting of Mn | 02-24-2011 |
| 20100288972 | RARE-EARTH DOPED ALKALINE-EARTH SILICON NITRIDE PHOSPHOR, METHOD FOR PRODUCING AND RADIATION CONVERTING DEVICE COMPRISING SUCH A PHOSPHOR - The invention relates to a method of manufacturing a rare-earth doped alkaline-earth silicon nitride phosphor of a stoichiometric composition. Said method comprising the step of selecting one or more compounds each comprising at least one element of the group comprising the rare-earth elements (RE), the alkaline-earth elements (AE), silicon (Si) and nitrogen (N) and together comprising the necessary elements to form the rare-earth doped alkaline-earth silicon nitride phosphor (AE | 11-18-2010 |
| 20080251764 | Carbidonitridosilicate Luminescent Substance - The invention relates to a luminescent substance consisting of a doped host lattice which absorbs at least one part of exciting radiation when it is excited by a high-energy radiation, thereby releasing an energy-poor emission radiation. 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. | 10-16-2008 |
