Scintillation and Luminescence Properties of the Zinc Oxide (ZnO) Doped Frit Crystal Under Gamma Radiation

The main objective of this study is to determine the characteristics of the scintillation and luminescent for Zinc Oxide (ZnO). Two groups of ZnO were prepared: pure (P338) and doped (P338Frit). This study investigates the scintillation and luminescent properties of the prepared ZnO in both powder and crystal forms. The NaI(Tl) scintillator is used as a tool for the control scintillator. It is a crystal that is commercially utilized in many radiation detecting fields. The P338 and P338Frit were used as the scintillator in the experimental setup. The P338 and P338Frit were bombarded with gamma photons of Am-241 and Cs-137. The set up was connected to Multichannel Analyzer (MCA) to analyse its gamma spectrum. The scintillation occurrence is followed by the occurrence of luminescence in order for photon interactions to be detected by the MCA system. The photons detected are called count. However, self-absorption of the light is common which prevail the count from being recorded even though the scintillation occurs. The Compton continuum and photoelectric peak of the interaction were not distinguished.In conclusion, the characteristics of the luminescence and scintillation IP: 111.93.1478 On: Wed 26 Aug 2020 05:48:23 for the prepared ZnO were observed, however, the gamma spetrm peaks recorded were inconclusive.
