Large Sb 2 S 3 inverse opals have been prepared that show extraordinary photonic behavior. A wide and well‐defined peak in the reflectance spectrum in the range 700–800 nm defines the most energetic full photonic bandgap in the literature. The homogeneity (see Figure) and degree of infiltration of the samples improve on those prepared by CBD methods.
