Crystal structure and optical properties of whitish pollucite bluephosphor

摘要

When the Eu2O3-added pollucite blue phosphor was produced last time in Aratmosphere,the quantum yield of the blue phosphor could be achieved up to 75%.However,there was a sample whose appearance was bright in a sample having a low maximumemission intensity but a large amount of addition.As a result,we have found burningconditions that look brighter to the human eye.
