Cadmium sulfide films were prepared by spray pyrolysis of thiourea complexe
s, and their optical, electrical, luminescent, and structural properties we
re investigated. The results are used to elucidate the mechanism underlying
the effect of the nature of the thiourea complex on the properties of the
films. The crystal structure and perfection of the films are shown to corre
late with the structure of the first coordination sphere of the thiourea co
mplex.
