Dielectric And Optical Properties

SrTiO3/ZnTiO3 heterolayered thin films were fabricated by spin coating Sr–Ti and Zn–Ti sol–gel precursors on fused silica substrate. The SrTiO3 and ZnTiO3 were coated alternatively to form ABAB heterolayered thin films. The thickness of individual layers was tailored by controlling the coating layers. The structure characterization of the thin films showed independent structure of each layer while the microwave dielectric properties and optical band gaps can be tuned by changing the layer configuration. The effects of the layer configuration on the dielectric and optical properties were studied.

In the present work, the microstructure and microwave dielectric properties of BaTi4O9 ceramics derived from a sol-gel precursor were presented. Density measuring results demonstrated that the largest densities of ceramic sample about 96.7% could be reached by virtue of a cool iso-static press and a sintering process at at 1300 °C for 6 hours. The dielectric constant (εr), quality factor (Q×f) and the temperature coefficients (τf) of the BaTi4O9 ceramic samples were 36.65, 28000 GHz, +20.2 ppm/°C, respectively. XRD, SEM and XPS were used to characterize the microstructure of the ceramics samples. Substantial Ti3+ was proposed to be the cause of dielectric loss.
