摘要

Quasiperiodic ferroelectric Pb Zr0.4 Ti0.6 O3 multilayers have been fabricated using the sol-gel technique based on one single precursor. The building block of the multilayer is the distinct Pb Zr0.4 Ti0.6 O3 /porous- Pb Zr0.4 Ti0.6 O3 bilayer formed in a single spin-casting/annealing step and the formation of the bilayer is governed by phase segregation process. The quasiperiodic ferroelectric multilayer exhibits good performance as a Bragg reflector. With 11 periods, 90% reflectivity and 40-nm stop-band width have been achieved at room temperature.
