Characterization of nanostructured dendritic silver bismuth sulfide produced by solvothermal reactions

摘要

Nanoparticles and nanostructured dendritic silver bismuth sulfide were successfully produced from silver acetate, bismuth nitrate, and thiosemicarbarzide in ethylene glycol by 140-200°C solvothermal reactions for 24-72 h. The phase was detected using X-ray diffraction (XRD) and selected area electron diffraction (SAED). Their SAED patterns were also in accordance with those of the simulations. Scanning and transmission electron microscopies (SEM and TEM) revealed the nanostructured products. Their photoluminescence (PL) emissions were detected at the same wavelength of 380 and 420 nm, although they were produced under different conditions.
