    摘要: An aspect of the present invention is directed to a system for use in oil well drilling applications. The system includes a scintillator material having a cubic garnet host and praseodymium distributed within the host. The scintillator material emits ultraviolet radiation in response to stimulating gamma ray radiation. A radiation detector optically coupled to the scintillator detects the emitted ultraviolet radiation. Another aspect of the invention is a method for detecting oil. A radiation detector is optically coupled to a scintillator material having a cubic garnet host and praseodymium distributed within the host, wherein the praseodymium acts as an activator, and wherein the scintillator material emits ultraviolet radiation in response to stimulating gamma ray radiation. The detector and the scintillator material are lowered below the surface of the earth, and ultraviolet radiation emitted by the scintillator material in response to stimulating gamma ray radiation reflected by hydrogen bearing compounds indicating the presence of oil is detected by the detector.

    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.
