Spectrally and temporarily resolved luminescence study of short-range order in nanostructured amorphous ZrO(2)

• The local structure amorphous ZrO(2) doped with europium (Eu(3+)) and its evolution during crystallization was investigated by using spectrally and temporally resolved luminescence of europium. A small contribution of a crystalline, tetragonal-like local phase emission to the overall broad/amorphous emission could be observed in the amorphous state before calcination. Also, a non-negligible amount of amorphous type emission was still detectable with the crystalline europium-doped ZrO(2) obtained on calcination at 500 and 1000 degrees C being assigned to a disordered, monoclinic-like local phase.
