摘要： A transmission mode x-ray diffraction screening system has a sample support that holds a sample tray with multiple samples to be tested. The sample support is connected to a translation stage that is movable in three dimensions, and that it offset from the location of the sample support. An x-ray source is located to one side of the sample support, and a detector is located to the other side, thereby allowing the detection of x-rays that are diffracted by the sample in a transmission mode. A retractable beamstop may be located between the sample and the detector to block at least part of the non-diffracted x-rays from the source. A video camera may also be provided for imaging the sample location, which may be illuminated by a laser. The entire system may be automated such that each sample in the sample tray may be sequentially analyzed.

摘要： A phosphor is provided that has a host material that is doped with a dopant having the chemical structure XCl 3 , where X is a rare earth element or combination of elements. A free oxygen contributor is also added to provide the free oxygen necessary to activate the rare earth dopant. The processing of the phosphor includes the heating of the phosphor in an overpressure environment of zinc, cadmium or tellurium. The heating is done in a two-temperature zone enclosed environment, so that impurities in the phosphor powder are condensed out on the cooler surface. Alternatively, the dopant may be a material that is not a rare earth element, such as copper, tellurium, cadmium, silver, potassium, manganese, magnesium, calcium, strontium, and barium.
