Abstract:
1. A scintillator, comprising: a first crystal phase including multiple columnar crystals; and a second crystal phase covering a side of each of the multiple columnar crystals, wherein the scintillator has a first surface and a second surface, which are not located on the same plane, wherein the first surface and the second surface each have a portion to which the second crystal phase is exposed, wherein the first crystal phase comprises a perovskite type oxide material including at least one element selected from the group consisting of Lu and Gd, and a rare earth element as an emission center, wherein the first crystal phase emits light by radiation excitation, and wherein the second crystal phase comprises alumina or a garnet type oxide material including A and B, where A is at least one element selected from the group consisting of Lu and Gd, and B is at least one element selected from the group consisting of Al, Sc, and Y.
