Deskripsi
Nanocrystals of ZnS preparing at 70, 75 and 80 °C have been characterized by X-ray diffraction (XRD), UV-Vis and Fourier transform infrared spectroscopy (FT-IR), atomic force microscopy (AFM) and field emission scanning electron microscopy (FESEM). The investigation suggests that aggregates of small spherical particles with an average size of 8 nm and well defined morphology were obtained at 80 °C. The particle size appears to increase with a decrease in synthesis temperature.
