Abstract
A scintillator crystal to be used for a radiation detector such as X-ray CT apparatus has a unidirectional phase-separated structure and provides a light guiding function without forming partitions to prevent any crosstalk. The scintillator crystal comprises a phase-separated structure including a plurality of first crystal phases of the columnar crystals with unidirectionality and a second crystal phase covering lateral surfaces of the first crystal phases. At least the second crystal phase comprises CuI and emits light when excited by radiation.
