Description
Summary:The photorefractive properties of SrxBa1-xNb2O6 (SBN, congruent composition x = 0.61) can be enhanced by doping with suitable polyvalent ions like Ce or Cr We report on optical absorption measurements in the UV-FIR region and on dielectric measurements in the temperature range 2-400 K as a function of the dopant concentration. The addition of a third doping component, photorefractive not active Li-ions, did not raise the ferroelectric phase transition temperature Tc.
