In this study, Sr1.94MgSi2O7: 0.02Eu2+, 0.04Dy3+ and Sr1.928MgSi2O7: 0.02Eu2+, 0.04Dy3+, 0.012Nd3+ long afterglow luminescent materials were successfully synthesized via the sol–gel method under reducing atmosphere at 1100°C for 3h. 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+.
