ZnO SCINTILLATOR AND METHOD FOR PRODUCING THE SAME, RADIATION DETECTOR, RADIATION INSPECTION APPARATUS, OR α-RAY CAMERA USING THE ZnO SCINTILLATOR

摘要

PROBLEM TO BE SOLVED: To provide a scintillator that has high amount of luminescence and high energy resolution and is useful for discrimination of α-ray sources.

SOLUTION: An impurity-doped ZnO single crystal scintillator that has high amount of luminescence and high energy resolution is obtained by producing a Cu-doped or Cd-doped single crystal using a method of liquid phase epitaxy in which a ZnO single crystal is grown by bringing a substrate into direct contact with mixed melt of solutes, ZnO and CuO or CdO, and a solvent. The radiation detector, a radiation measurement device, and an α-ray camera including the impurity-doped ZnO single crystal scintillator are provided.
