In this work, grass-like, needle-like and chrysanthemum-like ZnSe nanostructures have been prepared by hydrothermal method at 200°C for 24 h successfully. With different amounts of diethanolamine, various morphologies of ZnSe formed. The structures, morphologies and crystal orientation of as-synthesised ZnSe nanostructures were characterised by X-ray diffractometer (XRD) and scanning electron microscope. The experiment result of XRD indicated that the structures of all as-synthesised ZnSe nanomaterials were cubic crystal. The field emission (FE) properties of as-synthesised samples were tested and the results revealed that the FE properties were influenced by the morphologies significantly. The FE measurement showed that the chrysanthemum-like ZnSe nanostructures had the best FE properties with a high field enhancement factor of 4328 and a low turn-on electric field of 3.4 V μm−1 among all the as-synthesised ZnSe nanostructures. The reaction mechanism of various morphologies ZnSe was also explained as follow.
