Growth and local structure analysis of ZnS nanoparticles

The ZnS nanoparticles synthesized using sol–gel method are characterized using XRD and SEM. The powder XRD analysis is done using the Rietveld method. The bonding feature of ZnS nanoparticles is analyzed using the maximum entropy method. The bonding between Zn and S is clearly visible in the 3D and 2D MEM maps. The electron density at the middle of the bond between Zn and S atom is found to be 0.433 e/Å3. The particle size of ZnS nanoparticles is also analyzed. There is a close comparison between the particle size estimated using XRD and SEM.
