ABSTRACT:
A mechanoluminescence material comprising a matrix of composite metal oxide containing strontium and aluminum, represented by the general formula SrM1Al6O11(wherein M1is an alkaline earth metal) or SrM2Al3O7(wherein M2is a rare earth metal), and further comprising, as luminescence centers, a metal selected from among rare earth metals and transition metals capable of emitting light when a carrier having been excited by mechanical energy returns to its ground state.
