PRODUCTION METHOD OF ZINC OXIDE CRYSTAL, ZINC OXIDE CRYSTAL, SCINTILLATOR MATERIAL AND SCINTILLATOR DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a method for shortening a service life which can be performed after crystal production of a zinc oxide crystal.SOLUTION: A fluorescence lifetime of light emission from a ZnO crystal after crystal production is controlled by irradiating a zinc oxide crystal with a gamma ray which is an electromagnetic radiation, to thereby produce the zinc oxide crystal.SELECTED DRAWING: Figure 2
