Fine cadmium sulfide(CdS)powder was prepared from metal alkoxide. Using this powder, CdS films were fabricated. The CdS films were investigated using X-ray diffraction(XRD)and scanning electron microscopy(SEM). The CdS powder was synthesized by sulfurization of Cd(OR)_2(R=CH_3, C_2H_5)or Cd(OH)_2, and Cd(OH)_2 was derived from the hydrolysis of Cd(OR)_2. CdS pastes were manufactured by dispersing the resultant CdS powder into a mixture of terpineol and ethylcellulose using a three-roll mill. CdS pastes were screen-printed on glass substrates and dried. The CdS films were heat-treated at 300-600℃ in a N_2 atmosphere, and examined by XRD. Preferred orientation in the[002]direction was observed for CdS films obtained from Cd(OH)_2. On the other hand, in the case of CdS films obtained from Cd(OR)_2, no preferred orientation was observed.
