A facile one-pot synthesis of size- controlled monodisperse lanthanide- hydroxide-at-SiO2 core/shell colloids is reported. The base-synthesized lanthanide-hydroxide-at-SiO2 particles are nonsticky enough to be well-suspended in solution, and they self-organize into 3D photonic crystals (see figure) that show a strong suppression of spontaneous emission in the photonic stop band.
