ABSTRACT In this study, Sr2MgSi2O7:Eu2+,Dy3+ long-afterglow luminescent materials have been successfully prepared via sol-hydrothermal method. The sample shows good crystallinity and optical properties. The sintering time and sintering temperature have great impacts on the crystallization process and luminescence properties. Further, adding of H3BO3 has been found to be good for formation of Sr2MgSi2O7:Eu2+,Dy3+ and appropriate amount of H3BO3 addition helps to improve the performance of the sample afterglow. Crystallization of the samples can be improved by changing the sintering system and method. GRAPHICAL ABSTRACT
