摘　　要：A series of cerium sulfides were successfully prepared using commercially available nanoscale CeO_2 as precursor, anhydrous Na_2CO_3 as dopants, CS_2 as sulfur source, under 600–800 oC, respectively. Properties of samples were investigated by means of X-ray diffraction（XRD）, scanning electron microscopy（SEM） and spectrophotometry. The results showed that corresponding γ-Ce_2S_3 with small size was obtained by using nanoscale CeO_2 as precursor; pure phase γ-Ce_2S_3 could be obtained under low temperature of 700 oC. Coloring properties of γ-Ce_2S_3 obtained under 800 oC were studied by researching γ-Ce_2S_3/PE and γ-Ce_2S_3/PVC composites, respectively. The results showed that satisfied coloring effects to PE and PVC were obtained by using 0.5 phr and 0.2 phr γ-Ce_2S_3, respectively.A series of cerium sulfides were successfully prepared using commercially available nanoscale CeO_2 as precursor, anhydrous Na_2CO_3 as dopants, CS_2 as sulfur source, under 600–800 oC, respectively.
