MULTILAYER ZnO SINGLE CRYSTAL SCINTILLATOR AND METHOD FOR MANUFACTURING SAME

摘要

Provided are a multilayer ZnO single crystal scintillator wherein the light emitting quantity is increased, and a method for manufacturing such scintillator. A multilayer body composed of ZnO semiconductor layers having different band gaps is manufactured, and a layer having a small band gap is made to have a thickness that permits ionization radiation, such as a rays and electronic rays, to enter the layer, thereby the light emitting quantity of the multilayer ZnO single crystal scintillator is greatly increased.
