Scintillation properties of (GaxAl1−x)2O3 ceramics

In this communication scintillation properties of (GaxAl1−x)2O3 (x = 1, 0.75, 0.5, and 0.2) ceramics are reported. The investigated samples have been fabricated through two-step spark plasma sintering. Their properties have been studied by means of pulse height spectra, scintillation time profiles, radio- and thermoluminescence. Although room temperature scintillation yields of the samples do not exceed 1000 ph/MeV, their scintillation decays appear relatively fast as compared to single crystals.
