    Abstract: A scintillator unit that can reduce crosstalk when the scintillator unit includes a plurality of scintillators and a radiation detector are provided. More specifically, a scintillator unit includes a reflective layer between a plurality of scintillators and the plurality of scintillators, wherein an adhesive layer and a low-refractive-index layer with a lower refractive index than the adhesive layer are located in this order on the scintillators between the scintillators and the reflective layer.

    Abstract: A scintillator crystal includes a plurality of first crystal phases, and a second crystal phase covering respective side surfaces of the first crystal phases. Each of the plurality of first crystal phases is a columnar crystal that includes a perovskite type oxide material containing both Gd and Tb, and emits light by being excited by radiation. The second crystal phase includes alumina. Assuming that a, b, and c respectively represent Gd, Al, and Tb in an element ratio among them that are contained in a total amount of substance of the scintillator crystal, the element ratio is within a range defined by (a, b, c)=(0.174, 0.795, 0.031), (0.207, 0.756, 0.037), (0.213, 0.775, 0.012), and (0.194, 0.795, 0.011) as vertexes in a ternary composition diagram.

    Abstract: Provided is a scintillator used for detecting radiation in an X-ray CT scanner or the like, the scintillator having a unidirectional phase separation structure having an optical waveguide function, which eliminates the need of formation of partition walls for preventing crosstalks. The scintillator has the phase separation structure including: a first crystal phase including multiple columnar crystals having unidirectionality; and a second crystal phase filling space on the side of the first crystal phase. The second crystal phase includes a material represented by Cs3Cu2[XaY1-a]5, where X and Y are elements which are different from each other and which are selected from the group consisting of I, Br, and Cl, and 0≦a≦1 is satisfied.
