Abstract

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.
