🎥 Breakthrough in Mechanoluminescence: Watch 2000 Cycles of Stretching Trigger a Stunning Luminescence Shift! 🔬✨

Mechanoluminescent (ML) materials are revolutionizing smart sensing, self-powered lighting, and flexible electronics—but how do they truly work? For the first time, our study captures direct experimental evidence of electron transfer-driven self-oxidation and self-reduction in Eu-doped ML composites.

This fascinating video reveals a remarkable color transition in ML materials after 2000 stretching cycles, providing unprecedented insight into triboelectric charge-driven luminescence shifts.

🔍 What Does the Video Show?

🔵 BPC@PDMS Film: Initially emits a blue glow (Eu²⁺), but after repeated stretching, it turns red (Eu³⁺), proving self-oxidation.
🔴 CPC@PDMS Film: Starts with a red emission (Eu³⁺), shifting to blue (Eu²⁺) over cycles, revealing the first direct evidence of self-reduction under mechanical stress.
⚡ Why Does This Happen? Interfacial triboelectric charge transfer alters the oxidation state of Eu ions, directly driving reversible luminescence changes.

🧩 Why Is This a Game-Changer?

🔬 First real-time observation of self-recoverable luminescence via electron transfer.
💡 Confirms the role of triboelectric effects in controlling mechanoluminescence.
🚀 New design strategies for high-performance flexible sensors, stress visualization, and energy-free luminescent displays.
🎯 Paves the way for future bio-integrated and self-powered luminescent systems.
