Abstract

SrAl2O4 : Eu2+, Dy3+ as a light-storage phosphor was prepared by a solid state reaction. Oxide fluxes were added in SrAl2O4 : Eu2+, Dy3+ in order to control the particle size and shape. The effects of sintering conditions and Eu2O3, Dy2O3 and flux contents on the phosphorescent property of SrAl2O4 : Eu2+, Dy3+ were discussed. The optimum synthesis conditions were discussed in terms of the initial intensity of phosphorescence of SrAl2O4 : Eu2+, Dy3+ because the attenuation constant in each sample did not change. As a result, the optimum conditions to fabricate SrAl2O4 : Eu2+, Dy3+ were 1,773 K, 3 h, 2 %-H2/ 98 %-Ar atmosphere, 0.4 mol% Eu2O3, 0.4 mol% Dy2O3, and 3 mol% B2O3 as a flux.
