Interfacial Triboelectricity Lights Up Phosphor‐Polymer Elastic Composites: Unraveling the Mechanism of Mechanoluminescence in Zinc Sulfide Microparticle‐Embedded Polydimethylsiloxane Films (Small 17/2024)

Mechanoluminescence The cover image illustrates that self-recoverable mechanoluminescence (ML) in ZnS:Cu microparticles embedded in PDMS is originated from electroluminescence of ZnS:Cu achieved through triboelectricity between alumina-coated particle surfaces and PDMS. This enables repeatable ML generation with a gentle touch, press, or stretch, without requiring substantial particle pressure or pre-irradiation with UV/blue light, significantly expanding ML applications by softness and repeatability.
