摘要：

In this study, Sr1.94MgSi2O7: 0.02Eu(2+), 0.04Dy(3+) and Sr1.928MgSi2O7: 0.02Eu(2+), 0.04Dy(3+), 0.012Nd(3+) long afterglow luminescent materials were successfully synthesized via the solgel method under reducing atmosphere at 1100 degrees C for 3 h. No phase structure effect of Sr2MgSi2O7, or significant lattice distortion occurred while a small amount of rare earth ions were doped. Moreover, co-doping Sr2MgSi2O7: Eu2+, Dy3+ with Nd3+ has virtually no effect on the morphology of Sr2MgSi2O7: Eu2+, Dy3+. Co-doping Sr2MgSi2O7: Eu2+, Dy3+ with Nd3+ has also no evident effect on the position of the fluorescence emission peak. However, the applied concentration of Nd3+ co-doping created deeper traps and enhanced the afterglow properties of Sr2MgSi2O7: Eu2+, Dy3+. (C) 2016 Elsevier Ltd and Techna Group S.r.l.
