Summary
Silicon is widely used in electronics and solar cell devices because of its excellent semiconductor properties. Also, the large refractive index value of silicon enables the development of photonic devices. Here, we present a protocol to fabricate monodispere spherical colloids made of silicon with diameters between 300 nm and 500 nm. We also report on a home-built confocal microscope we have developed for the optical characterization of the nanoparticles. The optical characterization tool allows for optical properties of tiny particles and structure as small as 250 nm to be obtained. The results reported in the associated publications demonstrate silicon colloids sustain well-defined Mie resonances with a magnetic response suitable for processing metamaterials and photonic crystals.Further details
