A new method is proposed for the production of photonic crystals with a thoroughly controlled photonic bandgap. The method is based on the synthesis of an A1-x B x photonic crystal with controlled parameter x based on two isostructural A and B photonic crystals such that the photonic bandgap of the A crystal is smaller and that of the B crystal is greater than the required bandgap. The method is exemplified in a (100 - x) mol % SiO 2-x mol % ZnO inverse opal, in which the relative stop-band width monotonically increases with parameter x.
