This study investigates the effect of Co content on the structural, luminescence, and ferromagnetic properties of sol-gel Zn{sub 1-x}Co{sub x}S{sub y} films by x-ray diffraction, photoluminescence, energy dispersive spectrometer, atomic force microscopy, and alternating gradient magnetometer measurements. It is shown that Co doping may lead to weakened intensity of the defect-related luminescence and the intensity of the defect-related luminescence decreases with increasing Co content. Changes in Co concentration are important issues for improving crystal quality of ZnS films. It is also found that the defects play important roles in determining the ferromagnetic characteristics of the Zn{sub 1-x}Co{sub x}S{sub y} films.
