    摘要: A scintillation detector comprising nano-scale particles of a scintillation compound embedded in a plastic matrix is provided. The nano-scale particles may be made from metal oxides, metal oxyhalides, metal oxysulfides, or metal halides. Methods are provided for preparing the nano-scale particles. The particles may be coated with organic compounds or polymers prior to incorporation in the plastic matrix. A technique for matching the refractive index of the plastic matrix with the nano-scale particles by incorporating nano-scale particles of titanium dioxide is also provided. The scintillator may be coupled with one or more photodetectors to form a scintillation detection system. The scintillation detection system may be adapted for use in X-ray and radiation imaging devices, such as digital X-ray imaging, mammography, CT, PET, or SPECT, or may be used in radiation security detectors or subterranean radiation detectors.

    摘要: Crystalline scintillator materials comprising nano-scale particles of metal oxides, metal oxyhalides and metal oxysulfides are provided. The nano-scale particles are less than 100 nm in size. Methods are provided for preparing the particles. In one method, used to form oxyhalides and oxysulfides, metal salts are dissolved in water, and then precipitated out as fine particles using an aqueous base. After the particles are separated from the solution, they are annealed under a flow of a water saturated hydrogen anion gas, such as HCl or H2S, to form the crystalline scintillator particles The other methods take advantage of the characteristics of microemulsion solutions to control droplet size, and, thus, the particle size of the final nano-particles. For example, in one method, a first micro-emulsion containing metal salts if formed. The first micro-emulsion is mixed with an aqueous base in a second micro-emulsion to form the final nano-scale particles.
