PRODUCTION METHOD OF RARE EARTH OXYSULFIDE, CERAMIC SCINTILLATOR AND ITS PRODUCTION METHOD, SCINTILLATOR ARRAY, AND RADIATION DETECTOR

摘要

A production method of rare earth oxysulfide comprising a step of mixing a rare earth compound with sulfuric acid and/or sulfate in such a proportion that sulfate ions are 0.75-1.75 mol to 1 mol of a rare earth element, thereby preparing a reaction solution to obtain a product; a step of calcining the product to obtain calcined powder; and a step of reducing the calcined powder to obtain rare earth oxysulfide.
