Abstract
In this work, we showed that doping of sesquioxide based ceramics (for instance, Y2O3) by heterovalent ions leads to altering of polarizations. It results in variation of refractive index and wave-front distortion due to presence of volumes with increased content of heterovalent ions. It also contributes to lowering of transmittance and increasing of scattering in ZrO2-, HfO2-, or CeO2-doped Y2O3 ceramic samples.
