  Synthesis of scintillating metal organic frameworks for the detection of radiation from subatomic particles

  The objective of this research is to develop fluorescent metal organic frameworks (MOFs) as scintillation materials for more efficient light output and detection of ionizing radiation

  such as neutrons

  alpha particles or gamma rays

  generated by fissile materials. MOFs are multidimensional porous structures

  which are synthesized from the covalent bonding of metal ions or metal oxide clusters with organic ligand linkers

  such as benzene dicarboxylates. The ligands will be chosen to have fluorescent characteristics

  when excited by radiation or energetic sub-atomic particles. We will explore the synthesis of new MOFs

  containing carboxylate ligands with unique conjugated chromophores

  and doped with heavy metal as triplet-state harvesters

  that we are proposing will result in stronger and possibly

  unique luminescence spectral features that will allow for the discrimination between different ionizing radiations from subatomic particles. Photo-

  catho- and radio-luminescence studies will be conducted on the materials

  and radiation mechanism(s) will be investigated.

  Auger and photoemission spectroscopies. The ability to monitor the electronic properties during growth allows precise online control of parameters essential to bandgap engineering. Ex situ analysis with SIMS (secondary ion mass spectroscopy) was used to study the diffusion characteristics of dopants and the incorporation of constituent materials with variations in epitaxial growth parameters for systems grown by GSMBE
