5 nm thiospinel FeIn2S4 nanocrystallines were prepared through a solvotherm
al process at 280 degrees C. Powder X-ray diffraction (XRD) and transmissio
n electron microscopy (TEM) reveal that the product was nanocrystalline FeI
n2S4 with cubic cell, and uniform spherical particle morphology. The factor
s to the formation of uniform FeIn2S4 nanocrystallines with a narrow size d
istribution were discussed also.
