摘要

The self-activated mechanoluminescence (ML) of oxysulfides MZnOS (M =Ca, Sr, Ba) is very weak, and bright ML from these hosts is usually achievedwith activator-doping strategy. Herein, a promising alkaline-earth-metalionblending strategy, instead of activator doping, is proposed to achieveintense and self-activated ML from MZnOS. Upon partially substitutingthe Ca~（2+） of CaZnOS with Ba~（2+） and vice versa, intense and eye-visible ML isachieved via exerting a small mechanical stimulus of 2 N onto the obtainedCa_(1-x)Ba_xZnOS (0 < x < 1). The luminescence center for ML of Ca_(1-x)Ba_xZnOSis intrinsic oxygen vacancy, so that Ca_(1-x)Ba_xZnOS can give off efficient andself-activated ML. Under optimum conditions, the maximum ML emissionof Ca0.84Ba0.16ZnOS is about 50-folds and 170-folds to that of CaZnOS andBaZnOS, respectively. Promisingly, Bi3+ can be incorporated into the latticeof Ca_(1-x)Ba_xZnOS, transferring ML center from the oxygen defects ofCa_(1-x)Ba_xZnOS to the activator of Ca_(0.96-x）Ba_xZnOS:Bi_（0.04）, and eventuallyenable further enhanced ML by about twofolds. This alkaline-earth-metal-ionblending strategy can also enhance Bi~（3+）-activated ML from M_（0.96）ZnOS:Bi_（0.04）,the maximum emission for ML of Ca0.80Ba0.16ZnOS:Bi0.04 is 36-folds and38 folds to that of Ca_（0.96）ZnOS:Bi_（0.04） and Ba_（0.96）ZnOS:Bi_（0.04）, respectively. Thiswork opens an avenue to develop new ML hosts and luminophores withefficient emission.
