Abstract

A method for calculating the x-ray diffraction patterns of cadmium sulfide nanoparticles with a disordered internal structure, a real surface, shape, and size is proposed within the kinematic theory of scattering. A computer analysis has revealed that the characteristic shape of the experimental x-ray diffraction patterns of cadmium sulfide films and powders is determined by a specific disordered nanoparticle structure differing from the crystal structures of wurtzite and sphalerite. According to the computer simulation, cadmium sulfide nanoparticles synthesized through chemical deposition have a shape similar to a hexagonal prism with a characteristic size of approximately 5 nm.
