Аннотация

Cu 2 ZnSnS x Se 4- x nanocrystallines have been synthesized via solvothermal route in ethylenediamine using CuCl, ZnCl 2 , SnCl 4 ·5H 2 O, 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 Cu 2 ZnSnS x Se 4- x (0≤ x ≤4) is a complete solid solution with single phase and uniform composition. The solid solutions Cu 2 ZnSnS x Se 4- x (0&lt; x &lt;4) are single crystalline nanoplates with the diameter of 20–50 nm. Raman spectra of the Cu 2 ZnSnS x Se 4- x nanocrystallines revealed that vibrating modes were modulated by x -values. Photoluminescence spectra of the as-prepared Cu 2 ZnSnS x Se 4- x nanocrystallines showed that one wide emission band with peak position around 1.40 eV which slightly changed with x -values.
