Intense red emitting mechanoluminescence from CaZnOS:Mn,Li with c-axis preferred orientation

Abstract

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.
