บทคัดย่อ

Mg2+-codoped Y0.6Gd2.4Al2Ga3O12:Ce (YGAGG:Ce,Mg) single crystal was grown by the Czochralski method and
its luminescence and scintillation properties were investigated. Temperature dependence of radioluminescence
(RL) yield and photoluminescence (PL) decay time was measured, and activation energy of thermal ionization
process was determined from temperature-dependent PL decay time measurement. YGAGG:Ce,Mg exhibited high
X-ray excited RL yield almost 5 times higher than BGO reference scintillator. Its light yield of 41,500 ph/MeV and
scintillation decay times of 12 ns (2%) + 52 ns (65%) + 207 ns (33%) were measured under excitation with 662
keV γ rays from 137Cs source. Afterglow and thermally stimulated luminescence characteristics are also
investigated
