Low-voltage and wide-tuning-range SiO₂/aniline electrically responsive photonic crystal fabricated by solvent assisted charge separation

Abstract

Electrically responsive photonic crystal (ERPC) in weak polar media had good performance due to less screening of Coulombic interaction, but its synthesis was a challenge because of the difficulty in...

Fast, highly chromatic, electrically responsive photonic crystal inks for displays

“…Considering the ratio of dielectric constant to solvent viscosity, PCb is one of the best choices for solvents. 46 The voltage E is used to change the lattice spacing of the device, thereby regulating the structural color of ERPCs. Taking all these factors into account, adjusting the colloidal potential is the most suitable means to promote the electrical response rate of ERPCs.…”

Van der Waals Colloidal Crystals

“…The corresponding experimental reflection data (the right panels of Figure 4a–c) showed good agreement with the theoretical prediction. In particular, the achieved PBG width in this work was a record‐high (i.e., 100 nm) among the colloidal photonic crystals in the fluidic phase [ 31,60–66 ] (Figure 4d). Optical microscopy images (Figure 4e–g) and SEM images (Figure 4h–j) present the assembled vdW colloidal crystals with various Au cores.…”

Visual simulation of opal using bond percolation through the weighted Voronoi diagram and the Ewald construction

“…This is primarily due to its composition of multiple colloidal layers on the scale of the visible light wavelength, forming what is known as colloidal polycrystalline. Concerning the optical property that diffracts visible light, research and development has been conducted for practical applications, such as quantum information processing [32] and electrophoretic color displays [3]. Opal also has been used in jewelry since ancient times and is thus invaluable, not only as a raw material from an industrial perspective but also as a cultural treasure from the historical and artistic perspectives.…”
