Abstract:
Visible‐light‐responsive photonic structures have been prepared in alcohol solvents by using silica‐modified PbS colloidal nanocrystal clusters (CNCs) as building blocks. Further modification of the PbS CNCs with a coating of silica allowed the dispersion of the particles into nonaqueous solutions. Repulsive electrostatic and solvation forces contribute to the self‐assembly of the PbS@SiO 2 spheres. The core–shell particles have optical properties similar to those of CNCs, and they can also be assembled into close‐packing films through simple drop‐casting on silicon substrates. Embedding droplets of such a PbS@SiO 2 colloidal solution in a polymer matrix produced solid composite materials with visible‐light‐responsive optical properties with potential applications as sensors and optical switches.
