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.

摘要： Strontium, calcium, strontium calcium, strontium calcium magnesium, calcium magnesium aluminates, and strontium borates activated with Pr3+ exhibit characteristics of quantum-splitting phosphors under VUV excitation. A large emission peak at about 405 nm under VUV excitation is used conveniently to identify quantum-splitting phosphors. Improvements may be achieved with addition of fluorides or boric acid as a flux during the preparation of the phosphors. It is also possible to predict improvement in quantum efficiency by observing the ratio of emission intensities at about 480 nm and about 610 nm.
