Abstract

A mechanoluminescent layer of a composite material based on a polymer of polymethyl methacrylate and a fine powder of phosphor SrAl₂O₄:(Eu²⁺,Dy³⁺) on the surface of polymethyl methacrylate is obtained. The mechanoluminescence of the composite layer under the action of short acoustic pulses and a mechanical impactor is studied. It is shown the composite layer has high efficiency of the mechanical-to-optical conversion.
