a SEM images of microstructure arrays (feature size 80 µm) with perimeter-to-area ratios (P/A, µm⁻¹) of 22, 12, and 5. b 3D optical microscope image of 80 µm microstructure arrays. c Dependence of ML intensity at the emission peak (521 nm) on P/A for films with concave and convex arrays (40 and 100 µm). d ML intensity at the emission peak (521 nm) vs. perimeter-to-area ratio P/A for concave arrays with feature sizes of 40, 60, 80, and 100 µm. e Same as (d) for convex arrays. Scale bars, 200 µm (a). Source data are provided as a Source Data file.
