摘要： Scintillator compositions useful for the detection of high-energy radiation, such as X, &bgr;, or &ggr; radiation, contain alkali and rare earth pyrotungstates. In particular, the pyrotungstate is a double tungstate containing an oxide of an alkali metal selected from the group consisting of Na, K, Rb, and Cs and an oxide of a rare-earth element selected from the group consisting of Y, Gd, La, and Lu. The scintillators are characterized by high light output, reduced afterglow, short decay time, and high X-ray stopping power.

摘要： The present invention is directed toward methods of making hierarchically-ordered complex structures and composites thereof. Such structures are generally ordered on multiple length scales. Typically, at least one length scale comprises mesoscale dimensionality. Such methods generally utilize an organized, directionally-oriented combination of multiple fields to fabricate such structures and articles of manufacture made by the above-described methods, and in applications using such articles manufactured by the above-described process. The present invention is also directed toward novel composites, structures, and articles of manufacture made by the above-described processes. In some embodiments, such structures are composites of two or more such hierarchically-ordered complex substructures. In additional or other embodiments, such hierarchically-ordered complex substructures are combined, or integrated into, other structures that would not be considered hierarchically-ordered complex structures taken separately.

摘要： Cerium-doped alkaline-earth hafnium oxide scintillator compositions have at least one alkaline earth metal selected from the group consisting of Ba, Sr, Ca, and combinations thereof. The scintillator compositions can be formed into a shape having porosity less than about 0.05 percent for improved transparency. The alkaline earth metal can be partially substituted with divalent and/or trivalent ions other than cerium. Hafnium can be partially substituted with divalent, trivalent, and/or tetravalent ions. The scintillators are characterized by high light output, short decay time, and high radiation stopping power. The scintillators can be used as detector elements in PET systems.
