“…where E T is the thermal activation energy (eV) of the trap depth, and T M is the temperature at which the TL peak is the maximum (K). 21,22 Thermal activation energies of the two sites are 0.78, and 0.94 eV. This result indicates the presence of two shallow trap states near the conduction band.…”

Mechanoluminescent materials can convert mechanical stress into light. Among these, elasticoluminescent materials are useful for monitoring periodic and repetitive events. However, the development of high-performance elasticoluminescent materials remains a significant challenge because of the lack of understanding of the structures and mechanisms underlying mechanoluminescent materials. To address this issue, we investigated the elasticoluminescence properties of Gd2O2S:Tb3+ through a comprehensive analysis using experimental and computational techniques. Using thermoluminescence spectroscopy and density functional theory, we observed that trap states within the bandgap are generated by the O2− and S2− anion vacancies, which contribute to mechanoluminescence. The observation of green mechanoluminescence (ML) characteristics in Gd2O2S:Tb3+ was accompanied by a meticulous analysis of their origins, which aligned significantly well with the computational results. These findings enhance our understanding of the origin of ML and provide a solid foundation for the development of next-generation high-performance ML materials, thus fostering advancements in various fields of advanced technology research.
