Paper Abstract

The phase transitions and the temperature dependent electronic properties of Bi3.25La0.75Ti3O12 (BLT) film have been studied by transmittance spectra from 80 to 480 K. Anomalies of the optical constants are observed at 160 K and 300 K, which can be ascribed to the phase transitions. The optical properties of SrBi2-xNdxNb2O9 (SBNN) ceramics with the Nd concentrations from 0 to 0.2 have been investigated by Raman scattering spectra and spectroscopic ellipsometry. It can be found that the lattice vibrations slightly depend on the Nd concentrations. Moreover, the optical band gap linearly increases with the Nd concentrations due to charge compensation by the Nd doping.
