SiO 2 opals of higher quality can be achieved by a procedure involving the stricter selection of SiO 2 spheres. Monodispersity of the spheres is one of the major factors for obtaining opals with interesting optical properties and large size. In addition, the infiltration process of TiO 2 into SiO 2 opal in order to form inverse opal structures (see Figure) is discussed.
