Antimony Trisulfide Inverted Opals: Growth, Characterization, and Photonic Properties

Inverse opals with a photonic bandgap in the visible are highly desirable, but difficult to realize, as a combination of transparency in the visible and a high dielectric constant is required. Antimony trisulfide is a chalcogenide with the required optical properties; inverse opals based on this material have been fabricated (see Figure) and characterized.
