Silicon colloids with diameters from 0.5 μm to 5 μm are synthesized. Because of their spherical shape and smooth surface they work as optical microcavities with well‐defined resonating modes in the near‐infrared range. Silicon colloids are also the building blocks of photonic sponges formed by disorder networks of microspheres of different sizes that scatter light strongly in a wide range of wavelengths
