Exciting light emission and measuring temperature with ultrasound - Phys.org

If mechanoluminescent materials are subjected to external mechanical stress, they emit visible or invisible light. Such excitation can occur due to bending or gentle pressure, for example, but also completely contact-free through ultrasound. In this way, the …
