We report that the co-doping of Li + ions significantly enhances the crystallinity and mechanoluminescence (ML) intensity of CaZnOS : Mn . The prepared CaZnOS : Mn , Li showed a preferred orientation of c-axis, and the particles possessed a plate-like morphology, which could be attributed to the layered structure of CaZnOS . At the same time, the ML induced by compressive load exhibited intense red emission and obvious intensity enhancement by the Li + co-doping.
