摘      要：This article reports a new phosphorescent material,CaZnOS:Cu,that exhibits two types of mechano-optical conversion:mechanical quenching and *** intense mechanical quenching of phosphorescence corresponding to mechanical stimuli can be achieved in CaZnOS:Cu within a short decay time *** time,it gradually changes to mechanoluminescence when a mechanical load is *** propose that the mechanical quenching and mechanoluminescence arise from the different roles of shallow and deep traps in CaZnOS:***:Cu has promising applications in monitoring mechanical stress in industrial plants,structures,and living bodies.
