- Abstract
- The single crystal scintillator of bismuth germinate (Bi4Ge3O12:BGO) was successfully grown by the conventional Czochraski technique. The characteristics of the grown BGO were evaluated and presented on the excitation, emission responses and energy spectra of the γ-rays from 241Am, 133Ba, 57Co, 22Na, 137Cs and 54Mn radio-isotopes. The energy resolution of grown BGO, ΔE/E, was estimated to be 12.1% at 662 keV of γ-ray for 137Cs nuclide. Compared to the commercial BGO crystal, we confirmed that the grown BGO has a good performance and is comparable to reference one.
