Abstract
Methods of scintillation, scintillation devices, and metal halide hybrids that may be used as X-ray scintillators. The metal halide hybrids may include organic metal halide hybrids, inorganic metal halide hybrids, or organic-inorganic metal halide hybrids. The metal halide hybrids may have a 0D structure. The metal halide hybrids may be in the form of one or more discrete crystals.
Claims18
A method for X-ray scintillation, the method comprising:
- irradiating a metal halide hybrid with high-energy radiation to convert the high-energy radiation to at least one of near ultraviolet light or visible light;
- wherein the metal halide hybrid comprises an organic antimony halide comprising a crystal according to Formula (I)—
- R2SbX5 Formula (I),
- wherein X is a halide, and
- wherein R is an organic ammonium cation, wherein the organic ammonium cation has a structure according to formula (IIa) or formula (IIb)—
- wherein each of R1-R10 is independently selected from a substituted or unsubstituted C1-C20 hydrocarbyl.
A device comprising:
- an electronic substrate;
- an imaging chip;
- a fiber-optic face plate, wherein the imaging chip is arranged between the electronic substrate and the fiber-optic face plate;
- and
- a scintillator screen comprising a metal halide hybrid, wherein the fiber-optic face plate is arranged between the imaging chip and the scintillator screen;
- wherein the metal halide hybrid comprises an organic antimony halide comprising a crystal according to Formula (I)—
- R2SbX5 Formula (I),
- wherein X is a halide, and
- wherein R is an organic ammonium cation, wherein the organic ammonium cation has a structure according to formula (IIa) or formula (IIb)—
- wherein each of R1-R10 is independently selected from a substituted or unsubstituted C1-C20 hydrocarbyl.
A scintillator screen comprising an organic antimony halide, wherein the organic antimony halide comprises a crystal according to Formula (I)—
- R2SbX5 Formula (I),
- wherein X is a halide, and
- wherein R is an organic ammonium cation, wherein the organic ammonium cation has a structure according to formula (IIa) or formula (IIb)—
- wherein each of R1-R10 is independently selected from a substituted or unsubstituted C1-C20 hydrocarbyl.
