摘要： To find out a crystalline material for a high speed scintillator in place of BaF2 and the like, and a method for producing the material at a low cost. A single crystal of (Zn1−xMx)O1+x (M: Al, Ga, In, Y, Sc, La, Gd, Lu) (x=0 to 0.0500), (Zn1−xM′x)O1+2x(M′: Si, Ge, Sn, Pb)(x=0 to 0.0250) or (Zn1−xCdx)O (x=0 to 0.0500) is used as a scintillator. Defects of a ZnO single crystal can be reduced by using a platinum inner cylinder in order for a solution not to directly contact with an autoclave, for reducing impurities in the ZnO single crystal and precluding impurities interfering with scintillation, and by using LiOH and KOH as a mineralizer. ZnO can be doped with Al2O3, Ga2O3, In2O3, Si, Cd or the like by adding those materials to a starting material for the hydrothermal synthesis. The doping amounts can be controlled by changing charging amounts thereof. The doping of those elements inhibits the emission of visible lights, which results in the efficient transformation of the excitation energy to the luminescence from a free exciton.

摘要： It is an object of the present invention to provide a pulling-down apparatus that can breed a crystal having good characteristics of scintillation. The apparatus retains in a container that can control an atmosphere a melting pot having a narrow hole at the bottom side thereof, an induction heating device, and a seed-holding device that holds a seed and is pulled down so that a crystal formed successively to the seed is pulled down. Concurrently, imaging devices are arranged that can pick up images of a solid-liquid interface between the crystal and a melt material, from different directions, and the seed-holding device can be travel along directions perpendicular to respective image pickup directions in a horizontal plane.
