英文摘要	Bi4ti3o12 (bto) and bi3.25in0.75ti3o12 (bto:in) thin films were prepared on fused quartz and lanio3/si (lno) substrates by chemical solution deposition (csd). their microstructures, ferroelectric and optical properties were investigated by x-ray diffraction, scanning electron microscope, ferroelectric tester and uv-visible-nir spectrophotometer, respectively. the optical band-gaps of the films were found to be 3.64 and 3.45 ev for the bto and bto:in films, respectively. optical constants (refractive indexes and extinction coefficients) were determined from the optical transmittance spectra using the envelope method. following the single electronic oscillator model, the single oscillator energy e-0, the dispersion energy e-d, the average interband oscillator wavelength lambda(0), the average oscillator strength s-0, the refractive index dispersion parameter (e-0/s-0), the chemical bonding quantity beta, and the long wavelength refractive index n(infinity) were obtained and analyzed. both the refractive index and extinction coefficient of the bto:in films are smaller than those of the bto films. furthermore, the refractive index dispersion parameter (e-0/s-0) increases and the chemical bonding quantity beta decreases in the bto and bto:in films compared with those of bulk.
