Abstract
We report the red-emitting mechanoluminescence (ML) materials based on the piezoelectric semiconductors MZnOS:Mn2+ (M = Ca, Ba) synthesized by solid-state reaction. Both of the CaZnOS:Mn2+ and BaZnOS:Mn2+ show red light emission upon the compressive load, and the CaZnOS:Mn2+ emits a more intense red ML light at the same condition. We propose it should be considered to the polar non-centrosymmetric crystal structure of CaZnOS.
