Abstract: Two ways of synthesing cadmium sulfide nano-particles are reparted. One way is that Cd(NO₃ )₂ solution is added in the dropwise way lo thesolution of NarS , the other is that Cd( NO₃)₂ solution is added in the dropwiseway lo the rigorously-stired solution conlaining NaS and water glass. Themorphology and phase ofcadimum sulfide nano-particles are delected by SEMand X-ray diffraction. The results show ihat the CdS nano-particles arespherical and spinulous respeclively. The spherical parlicles are poor crys-talline with somewhal of oxidalion, and the spinulous particles are wurlzitestructure.
