Mechanoluminescence enhancement of the layered-structure compound Sr3Sn2O7:Sm3+ by H3BO3addition

Abstract

We report mechanoluminescence (ML) properties in the layered-structure compound Sr3Sn2O7:Sm3+. In this study, boric acid (H3BO3) was used as a flux in sintering process. By this step, we successfully enhanced the ML intensity of Sr3Sn2O7:Sm3+ to 6-times as large as that of the samples without using H3BO3. It was also found that the addition of H3BO3 leads to an anisometric shape of Sr3Sn2O7:Sm3+ particles, which may contribute the enhancement of ML intensity.
