Su Yeon Lee, Shin-Hyun Kim, Hyerim Hwang, Jae Young Sim, and Seung-Man Yang, "Controlled Pixelation of Inverse Opaline Structures towards Reflection-Mode Displays," Advanced Materials, accepted for publication (2014). (Corresponding author)

Pixelated inverse opals with red, green, and blue colors were prepared by hybridizing convective assembly of colloidal particles and photolithography techniques. The brilliant structural colors, high mechanical stability, and small feature size of the pixels were simultaneously accomplished, thereby providing color reflectors potentially useful for display devices. Moreover, this hybridized method provides a general means to create multi-colored photonic crystals.
