A colloidal crystal with fundamental photonic stopband in the near-infrared and higher-frequency photonic bands in the visible was designed to yield impressive sensitivity to stacking fault formation, as reported by Geoff Ozin and co-workers on p. 1110. Diagnostic patterns of brilliant colors emerge, providing a powerful spectroscopic tool to elucidate the origin, nature, and control of stacking faults.
