By using the floating zone method, we synthesized Sn-doped yttrium aluminum garnet (YAG). The nominal concentration of Sn was 10% with respect to Y, and the sample rod was cut along the growth direction. By the segregation phenomenon, we finally obtained Sn-0.6-, 1.0-, 1.2-, 1.4-, and 3.0%-doped YAG specimens with a diameter of 3 mm and a thickness of 1 mm. When we irradiated them with X-rays, a broad emission peaking at 420 nm was observed, and a similar spectral shape was observed in the photoluminescence (PL) emission spectrum. The decay times in PL and scintillation were 5 to 10 μs. Taking into account these data and possible emission origins in this chemical composition, we concluded the emission origin to be Sn2+.
