Abstract:

Monodispersed ZnS microspheres were hydrothermally synthesized under low temperature using zinc acetate and sodium thiosulfate as raw materials, and cetyltrimethyl ammonium bromide (CTAB) as surfactant. The particles were characterized by XRD, TEM, SEM and FT-IR. The results showed that the smooth particles were of cubic phase, well-dispersed and had uniform size of 3 μm in diameter, and the characteristic absorption peaks of Zn—S appeared in the FT-IR spectra. Also, the possible growth mechanism was discussed.

Key words: ZnS, hydrothermal synthesis, microspheres, growth mechanism
