| Popis: | KCu3S2 microslabs and microbelts have been synthesized using a composite-hydroxide mediated (CHM) approach without the presence of an organic surfactant. X-ray powder diffraction results indicate that the belts possess a monoclinic KCu3S2 crystalline structure. Scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM) were used to obtain detailed characterization of the microstructure and nanostructure of this material. Measurements of the UV–vis absorption spectrum have been performed, and the results reveal that this material is semiconducting with a bandgap of 1.459 eV. |
