WebReal-time visualization of stress-sensing can be potentially realized by mechanoluminescence (ML) materials that are able to transform mechanical stimulates into luminescence. The unsatisfactory ML brightness, however, restricts such applications of ML materials mainly to dark-field scenarios. Thanks to the Journal of Materials Chemistry C … WebThe bright-field methods have the problem that the illumination background light affects the measurement sensitivity. The dark-field measurement methods can remove the illumination background light, and the defect detection sensitivity is higher. However, the surface shape information is also removed out, thus the defect depth information is ...
