Abstract

Optical properties of Ferroelectric lead zirconate titanate [PZT, Pb(Zr,Ti)O3] films prepared on glass substrates at room temperature by aerosol deposition (AD) were investigated. The reflectance and transmittance of PZT films were measured in the wavelength range from ultraviolet to near infrared. Optical absorption of as-deposited films was found to be larger than that of the annealed films in the near infrared wavelength range. The results analyzed using optical models with the measured spectra indicate that the band gap energy of the PZT film increases with annealing.
