Structure and Morphology of Cds Nanoparticles
- 5 Downloads
The structure and morphology of CdS nanoparticles obtained by the hydrothermal synthesis are studied at temperatures of 80 °С, 100 °С, 120 °С, and 140 °С. The analysis is performed by calculating X-ray diffraction patterns by the Debye formula followed by the optimization of model parameters of nanocrystals. It is shown that with increasing temperature the CdS structure gradually transforms from a very defective sphalerite-like structure to very defective wurtzite-like one. At all temperatures the particles are ellipsoids stretched along the perpendicular to packing defects. An increase in the temperature causes a gradual enlargement of nanoparticles.
