Abstract

Pixelated patterns of photonic hemispheres are prepared by self-organization of silica particles in photocurable hemispherical droplets. Especially, RGB-color patterns with high coverage are fabricated by spotting 3× without coalescence and multicolored hemispheres are prepared by controlled coalescence. In addition, monodisperse photonic balls are prepared through the evolution of wettability of the suspension droplets.
