Abstract

We have studied scintillation properties of Eu³⁺-doped Gd₃Al₂Ga₃O₁₂ single crystals. Gd₃Al₂Ga₃O₁₂ single crystals with different concentrations of Eu³⁺ (0.5%, 1.0%, 5.0%, 10.0%, and 15.0%) were grown using the floating-zone method. In photoluminescence (PL) and scintillation properties, the Eu-doped Gd₃Al₂Ga₃O₁₂ single crystals showed emission peaks and several millisecond decay times due to 4f–4f transitions of Eu³⁺ ions. Pulse height spectra of all the samples were investigated under γ-ray irradiation from ¹³⁷Cs (662 keV). The 0.5%, 1.0%, 5.0%, and 10.0% Eu-doped samples showed full energy peaks. Among all the samples, the 5.0%
