摘要:A series of ZrS3 samples have been synthesized from elements at temperatures from 350 to 650°C. Stable ZrS3 colloid dispersions in different organic media (acetonitrile, dimethylformamide, ethanol, and isopropanol) were obtained from the polycrystalline samples. The structural and spectroscopic identities of the ZrS3 particles were confirmed by X-ray powder diffraction and Raman spectra. The sizes and morphology of particles in the colloid dispersions have been studied by transmission electron microscopy and dynamic light scattering method; the concentrations of the dispersions were found to depend on condition of synthesis of the initial bulk ZrS3.
