Group Ⅱ-Ⅵ semiconductor CdS with a direct band gap of 2.4 eV at room temperature has attractive photonic properties
which is suitable for window layer and buffer layer material of solar cells.CdS nanocrystalline films were grown on glass substrates by means of chemical bath deposition technique with CdCl

as the Cd ions and(NH

CS as the S ions source.The concentration of Cd ions
deposition temperature
deposition time and pH value have effects on quality of CdS nanocrystalline films.UV-Vis absorption spectra and PL spectra indicate that the change of concentration of Cd ions
deposition temperature
deposition time and pH may adjust the band-gap of CdS nanocrystalline films.
