Abstract In this study, Ce-doped SrAl 2 O 4 (Ce:SrAl 2 O 4 ) crystals were prepared by a floating zone (FZ) method and experimental evaluations were performed for scintillator applications. In photoluminescence (PL) with an excitation around 320 nm, an intense broad emission peak appears around 380 nm due to the 5d-4f transitions. The PL decay time constants are approximately 30 ns. The X-ray induced scintillation spectrum also shows an intense broad emission peak around 380 nm. Among the… CONTINUE READING
