[en] The Ce-doped lutetium pyrosilicate (LPS) scintillator is promising materials with high light outputs (Stable in wide temperature range up to 400 K) and sufficient energy resolutions. However, the Ce:LPS scintillator has intrinsic background from "1"7"6Lu. To obtain smaller intrinsic background and higher effective atomic number, new scintillation material of general formula Ce:(Lu, Yb)_2Si_2O_7 was studied. First, the Ce-doped (Lu_1_-_x, Yb_x)_2Si_2O_7 (0 ≤ x ≤ 1) sintered compacts were prepared by the solid-phase reaction method, and then (Ce_y, Yb_1_-_y)_2Si_2O_7 (y=0.00, 0.01) single crystals were grown by micro-pulling-down method. The result of powder X-ray diffraction analysis was consistent with previous data. The photo- and radio-luminescence spectra were measured, and the emission spectra were changed by replacing Lu to Yb. The Ce"3"+ 5d-4f emission intensity decreased, however, the newly emission peaks were observed, which the near-infrared emission peaks at 980 nm and 1030 nm and charge transfer emission peaks at 420 nm and 580 nm due to Yb"3"+.
