ZnO nanoballs synthesized from a single molecular precursor via non-hydrolytic solution route without assistance of base, surfactant, and template etc

ZnO nanoballs were synthesized by a single step solution route without assistance of base, surfactant, and template, etc., at relatively very low temperature. Defect-free ZnO nanoballs were obtained by selecting a suitable solvent mixture for the single crystal growth in bulk, which are quite different from other reports in the literature. The experimental results reveal that the ZnO crystal growths are more sensitive to the mixture of solvents, which depends on the miscibility, polarity and homogeneity of precursor in the reaction medium.
