TOP as ligand and solvent to synthesize silver telluride nanosheets

• Silver telluride nanosheets were prepared through one-pot synthetic strategy.
• TOP as both ligand and solvent favors silver telluride nanosheets growth.
• The I–V curve of an Ag2Te-nanosheet film indicates that as-prepared Ag2Te nanosheets have good electric conductivity.

Ag2Te nanosheets are synthesized by a simple one-pot route using trioctylphosphine (TOP) as both solvent and stabilizer. Various controlling parameters were examined, such as molar ratios of AgNO3 to tellurium powder, reaction temperature and time, and precursor concentration. The morphology and composition of the products were characterized by X-ray diffraction, field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, and transmission electron microscopy. On the basis of a series of synthesis and characterizations, the formation mechanism of the Ag2Te nanosheets are discussed. The I–V curve of an Ag2Te-nan osheet film indicates that as-prepared Ag2Te nanosheets have good electric conductivity.
