LAMINATE-TYPE ZINC OXIDE-BASED SINGLE CRYSTAL SCINTILLATOR AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a laminate-type ZnO-based single crystal scintillator whose emission amount is increased, and a method for manufacturing the same.

SOLUTION: The emission amount of a laminate-type ZnO-based single crystal scintillator 110 is significantly increased by manufacturing a laminate of a ZnO-based semiconductor with different band gaps and by making a layer with small band gap have a thickness of 5-50μm, into which thickness ionizing radiation, such asα-rays and electron rays can enter. The composition of the ZnO-based single crystal is (Znc1-x-yMgxCdy)O, wherein 0≤x≤0.145 and 0≤y≤0.07.
