1 Introduction Mechanoluminescent (ML) platforms are bringing us closer to a glowing future, enabling battery-free light emission in both ambient and low-light environments for applications ranging from sportswear and safety garments to pressure-responsive luminescent sensors [1-3]. In particular, ZnS-based phosphors have emerged as leading candidates for high-performance ML platforms owing to their high brightness and excellent mechanical reproducibility [4-6].
