Based on the phase separation, a series of quasiperiodic PbZr 0.4 Ti 0.6 O 3 (PZT) multilayers consisting of the ordered alignment of the dense PZT and porous PZT layers have been grown using one single precursor. The multilayers exhibit good performance as a dielectric mirror, and the position of the reflection maximum can be easily tuned over the whole visible range through varying the spinning rate. More than 86% optical reflectivity and less than 19 nm photonic stop‐band width have been achieved at room temperature. The quasiperiodic PZT multilayers can be used as dielectric reflectors, interference filters, and optical cavities.
