Seeing Sound and Vibrations. Ghent University
Certain light-emitting materials (or phosphors) are able to internally store energy for a long time.
Upon mechanical stimulation, such as pressure or scratching, some can emit this energy in the
form of visible light. These mechanoluminescent (ML) phosphors only start to show their full
application potential.
The first goal is to use these phosphors for the visualization of ultrasonic fields. Ultrasound,
