Boosting Mechanoluminescence Performance in Doped CaZnOS by the Facile Self-Reduction Approach.

ABSTRACT: Mechanoluminescence (ML), the emission of light under mechanical stimuli, shows great potential in passive sensing, wearable devices, and biomedical diagnostics. However, the practical application of ML materials is hindered by low intensity and poor self-recoverable performance. Herein, a Mn⁴⁺→Mn²⁺ self-reduction strategy is presented to significantly enhance the self-recoverable ML performance of CaZnOS by inducing lattice defects and promoting distortion in its noncentrosymmetric hexagonal structure. This approach enhances the internal piezoelectric response and increases the maximum ML intensity up to 4 times.
