Abstract
In this study mesoporous Sr2MgSi2O7:Eu2+, Dy3+ energy storage carriers were successfully prepared using cetyl trimethylammonium bromide (CTAB) as a template. Mesoporous Sr2MgSi2O7:Eu2+, Dy3+ can be obtained at a relatively low temperature of 950 °C with the addition of CTAB. The sample shows good porosity and energy storage performance. The pore diameter of the sample is distributed uniformly from 2 to 11 nm. The optical storage capability of the samples was investigated by studying the photoluminescence decay curves, which revealed that the afterglow time of the product could be improved by optimizing the amount of CTAB. Porous Sr2MgSi2O7:Eu2+, Dy3+ can therefore serve as a promising energy-storage carrier.
