Abstract
Ferroelectric inverse opals are promising candidates for tunable photonic crystals due to their electro-optical and elasto-optical properties. In this work, inverse opal photonic crystals of (Pb0.9La0.1)(Zr0.65Ti0.35)O3 (PLZT) were prepared through a self-assembled template replication procedure on a large area (typically 2cm × 1cm). The annealing process was optimized. The surface and cross-section were studied by a scanning electron microscope (SEM). X-ray Diffraction (XRD) results proved that PLZT in the ferroelectric perovskite phase was obtained. A band gap was observed in the transmission spectra and compared with the theoretical value.
