Abstract
Periodic ferroelectric multilayers consisting of alternating stack of the dense and porous Ba0.9Sr0.1TiO3 layers have been fabricated by spin-coating and annealing sol-gel techniques using one single precursor. With 16 periods, the Ba0.9Sr0.1TiO 3 multilayers exhibit excellent performance as dielectric mirrors: symmetric peak reflectivities of above 95% and flattopped stop bands of about 75 nm. The reflectance peak position is tunable through varying the spinning rate in the spin-coating process. The lead-free Ba0.9Sr 0.1TiO3 multilayers show high stability.
