Abstract

Cu2ZnSnSxSe4-xnanocrystallines have been synthesized via solvothermal route in ethylenediamine using CuCl, ZnCl2, SnCl4$\Cdot$5H2O, Se, and S powders as reaction reagents. The as-synthesized products were characterized by X-ray powder diffraction, transmission electron microscopy, and high-resolution transmission electron microscopy. The results confirm that the Cu2ZnSnSxSe4-x($0\leq x \leq 4$) is a complete solid solution with single phase and uniform composition. The solid solutions Cu2ZnSnSxSe4-x($0< x <4$) are single crystalline nanoplates with the diameter of 20--50 nm. Raman spectra of the Cu2ZnSnSxSe4-xnanocrystallines revealed that vibrating modes were modulated by $x$-values. Photoluminescence spectra of the as-prepared Cu2ZnSnSxSe4-xnanocrystallines showed that one wide emission band with peak position around 1.40 eV which slightly changed with $x$-values.

13. Fabrication of ZnS0.6Se0.4 Nanowires Using ZnS Nanowires as an In-situ Template.

Abstract

Single-crystalline ZnS0.6Se0.4 was synthesized by thermal evaporation without a metallic catalyst. The as-prepared ZnS0.6Se0.4 nanowires with a rough surface and a larger diameter were in contrast to the as-prepared ZnS nanowires. The growth mechanism for ZnS0.6Se0.4ZnS nanowires appears to be reasonably explained by the vapor–solid growth mechanism involved in ZnS nanowires, which serve as in-situ source templates. The cathodoluminescence properties of ZnS0.6Se0.4 reveal a broad emission band. The emission band of ZnS0.6Se0.4 nanowires exhibits a redshift in comparison with that of ZnS nanowires.

Abstract

Cu2ZnSnSxSe4-x nanocrystallines have been synthesized via solvothermal route in ethylenediamine using CuCl, ZnCl2, SnCl4·5H2O, Se, and S powders as reaction reagents. The as-synthesized products were characterized by X-ray powder diffraction, transmission electron microscopy, and high-resolution transmission electron microscopy. The results confirm that the Cu2ZnSnSxSe4-x (0≤x ≤4) is a complete solid solution with single phase and uniform composition. The solid solutions Cu2ZnSnSxSe4-x (0< x <4) are single crystalline nanoplates with the diameter of 20–50 nm. Raman spectra of the Cu2ZnSnSxSe4-x nanocrystallines revealed that vibrating modes were modulated by x-values. Photoluminescence spectra of the as-prepared Cu2ZnSnSxSe4-x nanocrystallines showed that one wide emission band with peak position around 1.40 eV which slightly changed with x-values.
