Fabrication Of High Quality Nanocrystalline Cd(1-X)Znxs Thin Films For Optoelectronic Applications

Nanocrystalline Cd(1-x)ZnxS thin films were prepared by spray pyrolysis technique. XRD studies showed that the films are polycrystalline and possess the hexagonal structure. The preferred crystallographic orientation of crystallites changes gradually from (002) to (101) with the increase in Zn composition. The AFM studies showed that the surface of the film is highly smooth and uniformly covered with the CdZnS nanoparticles. UV-VIS studies confirm the high quality of films. The band edge of these films is blue-shifted with the increase in Zn composition.
