摘要：

Eu-doped strontium aluminates (SrAl2O4: Eu2+) has been attracting attention as a highly potential mechanoluminescent (ML) material in a wide range of applications such as visualization of stress distribution for the concretes, steel materials, etc. In this study, we examined the single effect by the addition of flux, boric acid (H3BO3), in the synthesis process for the improvement of the ML intensity of SrAl2O4: Eu2+. Crystal structure, photoluminescence and ML properties were examined at various H3BO3 concentrations. It was found that the addition of H3BO3 provided 2.5 times improvement of ML intensity. This is probably due to the increase in the trap concentration. (C)2017 The Ceramic Society of Japan. All rights reserved.
