Mt. Iide over Niigata, Yamagata and Fukushima prefectures is known as a rich mine for silica sand. In this study, we adopted natural resource (silica sand from Mt. Iide, Osodani area) as a starting material for the synthesis of akermanite type long-persistent phosphor Sr2MgSi2O7: Eu2+, Dy3+. The silica sand derived (Sr0.98Eu0.01Dy0.01)2MgSi2O7 showed long afterglow phenomena. Therefore, the silica sand can be potentially used in preparing silicate phosphors.}, pages = {442--445}, title = {シリカサンドからの蛍光体の合成}, volume = {113}, year = {2006} }
