Abstract
PURPOSE: To produce a divalent Eu-activated blue fluorescent substance with high radiation efficiency and high luminance under excitation using ultraviolet-, cathode-, or X-rays by mixing precursors of MgO, Al2O3, and Eu2O3 which can be converted into these oxides at high temperature and Ba halide in a specified ratio and calcining the mixture in two steps.
