dc.description.abstract | Ultrafine ordered and disordered SrZrO3 powders were prepared by the polymeric precursor method. The structural evolution from structural disorder to order was monitored by X-ray diffraction and X-ray absorption near-edge spectroscopy. Complex cluster vacancies [ZrO5 center dot V-O(Z)] and [SrOII center dot V-O(Z)] (where V-O(Z) = V-O(X), V-O(center dot) and V-O(center dot center dot)) were proposed for disordered powders. The intense violet-blue light photoluminescence emission measured at room temperature in the disordered powders was attributed to complex cluster vacancies. High-level quantum mechanical calculations within the density functional theory framework were used to interpret the experimental results. (C) 2008 Acta Materialia Inc. Published by Elsevier Ltd.
