Water resistance of mechanoluminescent material particles

Abstract In an aqueous solution, mechanoluminescent (ML) material faces a serious problem as it deteriorates and loses its ML property. However, the author found that ML material particles that were impregnated with non-ionic polyhydric alcohol surfactant showed no deterioration in 0.1 to 0.01 M HNO3 aq. In addition, the filtrated particles from the immersion liquid showed water resistance.
