The silica sand is primarily composed of high purity SiO_2. 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 Sr_2MgSi_2O_7: Eu^<2+>, Dy^<3+>. The silica sand derived (Sr_<0.98>Eu_<0.01>Dy_<0.01>)_2MgSi_2O_7 showed long afterglow phenomena. Therefore, the silica sand can be potentially used in preparing silicate phosphors.
