Abstract
Striking color changes in the visible spectrum are produced when the voids of three-dimensionally ordered macroporous (3DOM) silica, alumina, and zirc onia ("inverse opals") are filled with solvents, it is reported here (see F igure). The wavelength of these colors is linearly related to the refractiv e index of the fluid filling the pores and can be tuned by modifying the re fractive index of the wall material as well as the size and spacing of the pores.
