Novel ZnSe nanosheets with tunable size and phase have been facilely synthesized via hydrothermal routes in the presence of neutral butylamine (BA) as structure-directing agent and ethylene diamine tetraacetic acid (EDTA) as stabilizer. The as-synthesized products were characterized via XRD, TEM, SEM and the UV-Visible absorption spectra. The results showed that the hydrothermal temperature and the dosage of BA had an important effect on the size and phase of the products. A possible formation mechanism for the ZnSe nanosheets was also discussed.
