    Abstract:

    PbZr0.4Ti0.6O3 multilayers with 16 periods have been grown on the glass substrates coated by transparent tin oxide doped with fluorine by using chemical solution deposition, and the micro-structures and optical properties of the multilayers have been investigated. The scanning electron microscope images show that the multilayers exhibit a smooth, dense and crack-free surface morphology, and a layered structure consisting of dense and porous PbZr0.4Ti0.6O3 layers. The X-ray diffraction curves of the PbZr0.4Ti0.6O3 multilayers show a single perovskite structure. The room temperature reflectance and transmittance spectra in the wavelength range of 350-900 nm display an optical reflection-band centered at 450 nm, with a peak reflectivity of 91% and a 41 nm stop-band width, and a transmission valley at 450 nm with the same band-width as the reflection band. The minimum of the transmittance is less than 6% in the valley. This investigation is helpful to enlarge the application scale of ferroelectric multilayers.
