    Abstract: A scintillation compound can include a rare earth element that is in a divalent(RE 2+ ) or a tetravalent state (RE 4+ ). The scintillation compound can include another element to allow for better change balance. The other element may be a principal constituent of the scintillation compound or may be a dopant or a co-dopant. In an embodiment, a metal element in a trivalent state (M 3+ ) may be replaced by RE 4+ and a metal element in a divalent state (M 2+ ). In another embodiment, M 3+ may be replaced by RE 2+ and M 4+ . In a further embodiment, M 2+ may be replaced by a RE 3+ and a metal element in a monovalent state (M 1+ ). Themetal element used for electronic charge balance may have a single valance state, rather than a plurality of valence states, to help reduce the likelihood that the valance state would change during formation of the scintillation compound.

    Abstract: A scintillation compound, other than a rare earth silicate, can include a rare earth element that is in a divalent (RE2+), trivalent (RE3+) or a tetravalent state (RE4+). The scintillation compound can include another element to allow for better change balance. The other element may be a principal constituent of the scintillation compound or may be a dopant or a co-dopant. In an embodiment, a metal element in a trivalent state (M3+) may be replaced by RE4+ and a metal element in a divalent state (M2+). In another embodiment, M3+ may be replaced by RE2+ and M4+. In a further embodiment, M2+ may be replaced by a RE3+ and a metal element in a monovalent state (M1+). The metal element used for electronic charge balance may have a single valance state, rather than a plurality of valence states, to help reduce the likelihood that the valance state would change during formation of the scintillation compound.

    Abstract: The invention relates to a material comprising a rare earth (Ln) silicate doped with an element B different from Ln, B being chosen among Ce, Pr, Tb, wherein B is at least partially in its 4+ oxidation state (B4+), the quantity of B4+ in said material being comprised between 0.0001 % and 0.1 % in mass. This material may be a scintillating material and may present an afterglow of generally less than 200 ppm after 100 ms relative to the intensity measured during an X-ray irradiation. It is preferably codoped. It may be obtained using an oxidizing annealing. It is particularly suited to integration in an ionizing particle detector that may be used in a medical imaging apparatus.
