<p><P>PROBLEM TO BE SOLVED: To provide a scintillator crystal having a unidirectional phase separation structure, which has an optical waveguide function of eliminating the need for forming a partition wall for preventing crosstalk in a scintillator used for detecting radiation such as an X-ray CT apparatus. <P>SOLUTION: The scintillator crystal has the phase separation structure comprising: a first crystal phase comprising unidirectional columnar crystal; and a second crystal phase that covers the side surface of the first crystal phase. One of the first and second crystal phases contains an oxide, and the other thereof contains a fluoride. The phase containing the oxide emits light by means of the radiation. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
