Abstract Details

2017, Master of Science, Ohio State University, Mechanical Engineering.
Perovskite crystals have been widely researched and applied in the field of solar cell engineering, and recently in the field of high energy photon detection. Within the nuclear detection industry, there is a desire for new, cost-effective materials for the use of gamma spectroscopy. This thesis sets out to produce a new hybrid inorganic – organic metal halide perovskite based, low-cost gamma spectroscopy detector. With the aid of Professor Haung’s group from the University of Nebraska-Lincoln, various perovskite device structures are fabricated and tested. To assist in the verification of the experimental results, the energy spectrum for the nuclear decay of the 137Cs isotope is generated through modeling of real-time pulse height analysis with simulation software Geant4. A well-defined 137Cs energy spectrum is acquired by using a CH3NH3PbBr2.94Cl0.06 single crystal at room temperature. The energy spectrum obtained, along with supporting data, provides evidence of how perovskite single crystal can successfully detect high energy photons. The low cost, simple synthesis, and excellent radiation hardness of the hybrid perovskites make them ideal candidates for radiation detector materials.
