Scintillation properties of a Pr-doped gadolinium lanthanum pyrosilicate (Pr:La-GPS) crystal grown by the floating zone (FZ) method were investigated, because the Pr3+ 5d–4f transition is expected to show a shorter decay time than the Ce3+ 5d–4f transition. In both α-ray radioluminescence and photoluminescence spectra, the emission peak related to the Pr3+ 5d–4f transition was observed at around 350 nm. The photoluminescence decay time of Pr:La-GPS was found to be as short as >23 ns, whereas Ce:La-GPS had a decay time of >31 ns.
