High sinterability nano-Y2O3 powders for transparent ceramics were successfully synthesized via the decomposition of hydroxyl-carbonate precursors from spray coprecipitation. The chemical composition of the precursor was determined as Y(CO3)(OH)·nH2O (n = 1–1.5), and it was evolved into Y2O3 particles with clear facets after calcination with the as...

Hexagonal prism-like Al-doped ZnO nanorods were prepared by a coprecipitation method followed by annealing. The effects of Al doping and annealing atmosphere on microstructure and optical properties were studied. X-ray diffraction (XRD) results show that the Al-doped nanorods have a pure hexagonal wurtzite structure and good crystallinity. Field em...
