Abstract: PAM-ZnS hybrid microspheres with diameters of 640-660 nm were fabricated in two simple steps: the formation of polyacrylamide(PAM) microspheres via the polymerization of acrylamide in the water phase of a water-in-toluene emulsion,and the sedimentation of ZnS at the inside or on the surface of the PAM microspheres in the emulsion via the reaction of Zn(AC)2 and Na2S or H2S.ZnS@PAM and PAM@ZnS hybrid microspheres were obtained by the use of Na2S and H2S as the precipitating agent respectively.The hybrid microspheres were characterized with TEM and FTIR spectrum.The XRD results show that ZnS in the hybrid microspheres is in a crystalline state with a face-centered structure.The hybrid microspheres are photoluminescence-active due to the presence of ZnS.
