Abstract
Cd1-xZnxS thin films were deposited on glass substrates by chemical bath deposition. The influence of x on the crystalline structure, surface morphology and optical properties of Cd1-xZnxS thin films were studied by measures of XRD, SEM, and spectrophotometer, respectively. The SEM images indicated that, with the increase of x, the particles of Cd1-xZnxS changed from small and compact to larger and sparser, which was thought to be the transformation of two reaction mechanisms in the deposition process, from ion-by-ion process to cluster-by-cluster process. The average transmittance values of Cd1-xZnxS samples in visible spectrum were all above 70%, and the band gaps of the Cd1-xZnxS thin films varied from 2.47 eV to 3.66 eV during the x from 0 to 1.
