Abstract:Tuning the lattice spacing or stop bands holds great significance in the design and application of materials with colloidal crystals. Typically, particle surface modifications or the application of external physical fields are needed. In this study, we demonstrated the ability to expand or compress the lattice of colloidal crystals simply by utilizing a salt solution, without the need for any special treatments to the colloidal particles. We found that by only considering the diffusiophoresis effect we cannot … Show more
Exploiting multiple scattering, we measure the time-dependent density profile of an opalescent but turbid colloidal crystal ball in particle-free environment.
