Title:
SCINTILLATION COMPOUND INCLUDING A RARE EARTH ELEMENT AND A PROCESS OF FORMING THE SAME
Document Type and Number:
WIPO Patent Application WO/2013/041251
Kind Code:
A4
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.
