Synthesis of ZnO nanosheets by room-temperature decomposition of a layered precursor synthesized by microwave heating

ZnO nanosheets with the wurtzite structure have been successfully synthesized via a microwaveassisted solution method. The thicknesses of ZnO nanosheets are in the range of 5–10 nm and lateral sizes up to 1 lm. The surfaces of ZnO nanosheets are ð1210Þ planes of wurtzite structure. The as-prepared products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM). The optical and thermal properties were investigated with UV–Visible absorption spectra, thermogravimetric analysis (TG) and differential scanning calorimetric analysis (DSC).
