- Abstract
This paper highlights our work on the recent progress in novel elastico-mechanoluminescence (EML) materials :2 and (4)2:2 , which can simultaneously "feel" (sense) and "see" (image) the applied mechanical stress as an intense and proportional luminescence. :2 can sense various types of mechanical stress, including ultrasonic vibration, impact, friction and compression because of the large piezoelectric coefficient. (4)2:2 with multiple trap levels shows a broad measurement range for dynamic load. Both of :2 and (4)2:2 belong to the defect-controlled type piezoelectric phosphors, and their EML mechanisms could be explained using the piezoelectrically induced carrier de-trapping model.
