Abstract

Pr³⁺ doped Lu₃Al₅O₁₂ crystalline scintillator is developed. By the gamma-ray irradiation, three different Pr³⁺ concentration, 0.1, 0.18, and 0.22 mol%, are compared in a view of light yield, energy resolution, and decay time. At the same time, a temperature dependence of these gamma-ray responses are also investigated. As a result, the 0.22 mol% sample shows the highest light yield, reaching more than three times as large as reference BGO scintillator, at +20 degrees of Celcius. A main component of the decay is ∼ 21 ns for all the sample pieces. The temperature dependence of these sample pieces is low. Gamma-ray responses at +20 degrees of Celcius are almost the same level for these three pieces, but the temperature dependences are different with Pr³⁺ concentration.
