Synthesis and Properties of ZnSe Precursor and ZnSe Nanoribbon Arrays on Zn Substrates

Well‐aligned ZnSe precursor nanoribbon arrays on zinc surface were fabricated via a solvothermal method using Zn foil as Zn source, Se powder as Se source and ethylenediamine (en) as solvent. The ZnSe nanoribbon arrays can be easily obtained by heating the ZnSe precursors in N2 at 300°C for 5 hours. The as‐prepared precursors as well as the annealed products are characterized by scanning electron microscopy and powder X‐ray diffraction. Field emission (FE) experiments on annealed sample are also carried out.
