PREPARATION AND CHARACTERIZATION OF TERNARY CADMIUM CHALCOGENIDES

摘要

Ternary cadmium chalcogenides were prepared using different methods: hydrothermal, microwave, and sonochemical synthesis in ethylenediamine (en) and different en/water solutions, as well as by direct reactions of elemental precursors and binary cadmium chalcogenides. The obtained ternary nanoparticles CdSexTe1-x (x = 0.1 and x = 0.6) were characterized by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM). The formation and transformation of ternary phases was studied by thermal analysis (TGA). The as-prepared chalcogenides were nanosized with different shapes and crystallite sizes between 6 and 35 nm, depending on the preparation method.
