Color Conversion: Mechanoluminescence Color Conversion by Spontaneous Fluorescent‐Dye‐Diffusion in Elastomeric Zinc Sulfide Composite (Adv. Funct. Mater. 27/2016)

S. M. Jeong and co-workers demonstrate on page 4848 the complete color conversion of mechanoluminescence (ML) from green to red using spontaneous fluorescent-dye-diffusion in zinc sulfide (ZnS) microparticles embedded in polydimethylsiloxane (PDMS) framework. The red luminescence could be achieved by 4-(dicyanomethylene)-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) fully absorbing green mechanoluminescence (ML) from ZnS. The straightforward approach may be applied to manipulate broader color expression for future ML applications.
