A series of
nanocrystalline thin films of cadmium zinc sulphide (Cd1-xZnxS) solid solution
were deposited on glass substrates using spray pyrolysis. Cadmium chloride
(CdCl2), zinc chloride (ZnCl2) and thiourea (NH2CSNH2) were used as the sources
of Cd, Zn and S respectively. The films were characterized using structural,
morphological and optical techniques. X-ray diffraction (XRD) studies show that
the films of Cd1-xZnxS are polycrystalline and single phase having the wurtzite
structure. The crystallites in the thin films of pure CdS possess preferred
crystallographic orientation along the <002> direction. The preferred
orientation of crystallites in the Cd1-xZnxS films changes from <002> to
<101> with increase in Zn concentration. The lattice parameters of
Cd1-xZnxS decrease with increase in Zn concentration. Scanning electron
microscopy (SEM) and atomic force microscopy (AFM) studies show that the
surfaces of the films are smooth and are uniformly covered with nanoparticles.
Energy dispersive analysis of xrays (EDAX) results reveal that the grown films
have good stoichiometry. Optical transmission spectra confirm the good quality
of the Cd1-xZnxS films.
