摘要:
Some embodiments of the present invention are directed toward nanocrystalline oxide-based phosphor materials, and methods for making same. Typically, such methods comprise a steric entrapment route for converting precursors into such phosphor material. In some embodiments, the nanocrystalline oxide-based phosphor materials are quantum splitting phosphors. In some or other embodiments, such nanocrystalline oxide based phosphor materials provide reduced scattering, leading to greater efficiency, when used in lighting applications.
摘要:
A system for storing and dynamically updating data represented in the Extensible Markup Language (XML) which separates the data values in at least some of the elements of an XML document and places those data values in relational database tables where they may be processed using conventional RDBMS techniques. The hierarchical structure of the XML document is saved separately in an XML skeleton object from which element data other than primary key values has been removed. The XML documents document type definition (DTD) is stored, along with additional property data used the RDBMS, in an XML Definition object. The additional property information includes the identification of primary key data values which are used to link the structural definition data to the value data stored in the tables, the designation of data types used for more efficient storage of data from predetermined XML elements, the designation of selected element data for indexing and for column storage, and the designation or relational integrity constraints which help insure that logically connected data is not inappropriately deleted or updated. The XML data as stored in the relational tables can be retrieved as a complete XML document, or selected XML elements can be retrieved by themselves, by merging the table data into the XML skeleton.

A portable tracing utility provides trace configuration, trace instrumentation and trace management functionality for single or multithreaded programs. Through various application programming interfaces (“APIs”) of the tracing utility, a client may control tracing behavior to setup in-memory data structures for storing trace records that record the program's history of execution or to alter the granularity of execution history being traced. The trace behavior can be modified during the life of a program by using the APIs, either dynamically when the program assumes certain states, or through remote procedure calls issued by, for example, an external interface. Programs are instrumented with these APIs to record the history of execution, which during execution of the program is stored in circular in-memory buffers.
摘要:
A phosphor comprises a material having a formula of AMgD10O17:Eu2+,Mn2+, wherein A is at least an alkaline-earth metal selected from the group consisting of Ba, Sr, Ca, and combinations thereof; and D is at least a metal selected from the group consisting of Al, Ga, In, and combinations thereof; wherein Eu2+ ions are present in an amount from about 10 to about 50 atom percent of a combined quantity of A ions and europium ions, and Mn2+ ions are present in an amount from about 5 to about 30 atom percent of a combined quantity of magnesium ions and manganese ions. The phosphor is used alone or in conjunction with other phosphors to convert UV/blue radiation emitted by a source, such as an LED or a gas discharge device, to visible light.
摘要:
A phosphor comprises an oxide that comprises: (a) at least an element selected from the group consisting of phosphorus and boron; (b) at least a metal selected from the group consisting of elements of Group IIIA, elements of Group IVA, and elements of the lanthanide series; which oxide is co-activated with Ce3+ and Tb3+. In one embodiment, a phosphor comprises lanthanum and gadolinium phosphate and/or borate co-activated with cerium and terbium. A phosphor of the present invention has low emission of UV radiation having wavelengths longer than about 250 nm, thus efficiently uses exciting UV having shorter wavelengths. The phosphor is used in light source that comprises a UV radiation source to convert efficiently UV radiation to visible light.

摘要:
The disclosed sensor chip includes a substrate and a moving member coupled to the substrate and disposed for movement relative to the substrate. The moving member moves relative to the substrate in a first direction and in a second direction in response to movement of the substrate. The first direction is different than the second direction. The moving member includes a plurality of receptors. The receptors are configured for selectively binding to a first measurand.
