PbZr 0.4 Ti 0.6 O 3 multilayer, comprising of three PbZr 0.4 Ti 0.6 O 3 stacks with a slight difference in their periodic thickness, has been designed and fabricated on FTO substrate based on one single chemical solution and on the simple spinning‐coating and annealing technique. The obtained multilayer exhibits a high reflectivity band with 110 nm photonic stop‐band width and average reflectivity of over 80% at room temperature, rendering the novel arrange of PbZr 0.4 Ti 0.6 O 3 multilayer system a promising candidate as tunable dielectric mirrors, optical cavities and selective filters.
