Abstract

© Springer International Publishing Switzerland 2015. Structural and optical properties of pure and Y-doped ZrO 2 nanopowders with different Y content sintered by co-precipitation of Zr and Y nitrates were investigated. It was observed that the increase of Y content stimulates the transformation of crystalline phase from monoclinic through tetragonal to cubic while the increase of calcinations time leads to the increase of ZrO 2 grain sizes. Generally, room temperature photo- and cathodoluminescence spectra showed several bands in blue–orange range. The increase of powder grains results in the enhancement of 2.81-eV photoluminescence caused probably by volume centers. Besides blue– orange emission, additional “red” cathodoluminescence band was observed. Its intensity exceeds essentially the magnitude of other components and increases with cooling. This “red” band was found to be complex and caused by intradefect transition. The excitation mechanism of this band is discussed.
