| description | In the present day, inorganic scintillators have been developed to detect high-energy photons such as x-rays and γ -rays. They have been applied in many works, such as astronomy, materials inspection, high energy physics, industrial application, and natural resources exploration. Especially in the medical field, they are used as radiation detectors in diagnostic equipment such as PET scanner, x-ray CT scanner, SPECT scanner, etc. This research studied the scintillation characteristics of Ce:GSO and Ce:LGSO single crystals. We found that at 662 keV gamma-ray energy, Ce:LGSO crystal has about 2.3 times more light yield than Ce:GSO crystal, but the energy resolution of both crystals is not different. For the degree of non-proportionality of both crystals, Ce:LGSO scintillator shows 0.08, which is better than the 0.19 obtained from Ce:GSO scintillator. This work also discusses the two scintillators’ peak-to-total ratio, loss parameter, and intrinsic light yield. |
