  • METHOD OF PREPARING MECHANOLUMINESCENT MATERIAL AND COMPOSITE MATERIAL CONTAINING IT
    Publication number: 20210009897
    Abstract: A method of preparing a mechanoluminescent material includes the steps of: a) providing a mixture including precursors of a base material, a fluxing agent, and at least one lanthanide ion; b) heat-treating the mixture to obtain the mechanoluminescent material; and c) optionally grinding the mechanoluminescent material into powder form; wherein the fluxing agent facilitates incorporation of the at least one lanthanide ion into the base material. A composite material includes a first mechanoluminescent material, wherein the first mechanoluminescent material includes at least 2-3 mol % of a lanthanide ion.
