Nanocomposites for Radiation Sensing
MetadataShow full item record
Transparent polymer and glass-matrix based nanocomposite scintillators were developed for scintillation applications. Quantum dot polymer composites, fluoride nanophosphor epoxy composites and halide nanoparticle containing glass composites were prepared and studied for gamma-ray spectroscopy, X-ray imaging, alpha particle and neutron detection. Scintillation behavior was observed in all the polymer and glass matrix nanocomposite materials, but the most promising systems are the glass-matrix scintillators. These materials show promise for applications in nuclear spectroscopy and radiation detection for nuclear physics, medicine and homeland security. We will discuss the synthesis and characterization of these nanoparticles, their incorporation into composites and results obtained for radiation detection.
