Large scale SnO microhydrangeas are obtained successfully through thermally evaporating of SnO2 powder wrapped by a filter paper at 1050°C and using gold coated Si wafer as the substrate. The as-obtained SnO microhydrangeas are consisted of many thin nanosheets with the thicknesses of 30–60 nm and the diameters of 500–600 nm. A vapor-liquid-solid (VLS) growth mechanism for the as-synthesized SnO microhydrangeas...
