Transparent polycrystalline ceramic scintillators and methods of preparing the same

Abstract

This invention relates to transparent polycrystalline ceramic scintillators and methods of preparing the same. The invention also relates to gadolinium-yttrium oxide ceramic scintillators with europium added as an activator, which are optically transparent and whose cubic structures are maintained even when gadolinium oxide constitutes more than 50% of the scintillator. The scintillators of the present invention also have high light yield due to excellent luminescent characteristics in the visible light region.
