More Information
Summary: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.
