A scintillator material for an ionizing radiation detector comprising a halide perovskite, said perovskite having one of the following formulations:

Scintillator material comprising a doped halide perovskite

A scintillation compound can include a rare earth silicate. The rare-earth silicate may be lutetium yttrium orthosilicate. The rare-earth silicate may be doped with Ce. The rare-earth silicate doped with Ce may include a rare-earth element in a tetravalent state at a concentration of at least approximately 10 ppm atomic of the scintillation compound.

Scintillation compound including a rare earth element and a process of forming the same

The invention relates to an inorganic scintillator material of formula LuYCeMSiM′O, in which: In particular, this material may equip scintillation detectors for applications in industry, for the medical field (scanners) and/or for detection in oil drilling. The presence of Ca in the crystal reduces the afterglow, while stopping power for high-energy radiation remains high.

Dense high-speed scintillator material of low afterglow

A scintillation compound can include a rare earth element that is in a divalent (RE) or a tetravalent state (RE). 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) may be replaced by REand a metal element in a divalent state (M). In another embodiment, Mmay be replaced by REand M. In a further embodiment, Mmay be replaced by a REand a metal element in a monovalent state (M). 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.

Persistent luminescence nanoparticles excitable in situ for in vivo optical imaging, in vivo multimodal optical&#x2014;MRI imaging, and theranostics

A ceramic scintillator body includes a polycrystalline ceramic scintillating material having a substantially cubic crystallographic structure. The polycrystalline ceramic scintillating material has a chemical composition represented by a general formula LUGdO:Ac, where x is greater than zero and less than two, and where Ac is an activator.

Ceramic scintillator body and scintillation device

A polycrystalline ceramic scintillator body includes a ceramic scintillating material comprising an oxide of gadolinium (Gd) and a second rare earth element (Re). The ceramic scintillating material has a composition, expressed in terms of molar percentage of oxide constituents, that includes greater than fifty-five percent (55%) GdOand a minority percentage Of ReO. The ceramic scintillating material includes an activator.

A scintillation device includes a free-standing ceramic scintillator body that includes a polycrystalline ceramic scintillating material comprising a rare earth element, wherein the polycrystalline ceramic scintillating material is characterized substantially by a cation-deficient perovskite structure. A method of producing a free-standing ceramic scintillator body includes preparing a precursor solution including a rare earth element precursor, a hafnium precursor and an activator (Ac) precursor, obtaining a precipitate from the solution, and calcining the precipitate to obtain a polycrystalline ceramic scintillating material including a rare earth hafnate doped with the activator and having a cation-deficient perovskite structure.
