Synthesis and Optoelectrochemical Properties of ZnS:Co Semiconductor Quantum Dots

YANG Xu1 ZHOU Hong2 SHEN Bin1, ZHANG Ling1(1School of Chemistry and Chemical Engineering,Southeast University,Nanjing 211189,P.R.China;2Biochemical and Environmental Engineering College,Nanjing Xiaozhuang University,Nanjing 211171,P.R.China)  
Co2+ doped ZnS semiconductor quantum dots(QDs) were synthesized in an aqueous solution at 70 ℃ using citric acid(CA) or mercaptopropionic acid(MPA) as a stabilizer.The as-prepared undoped and the Co2+ doped ZnS quantum dots(QDs) were characterized by UV-Vis spectrum,photoluminescence(PL) spectrum,X-ray powder diffraction(XRD),cyclic voltammetry,and transmission electron microscopy(TEM).We studied the dependence of the doped ZnS quantum dots photoluminescence on the dopant and the dopant concentration.Results show that Co2+ ions are doped mainly on the ZnS nanocrystal′s surface and as a result,the band-edge and surface defect emissions of the ZnS quantum dots are substituted by a Co2+-related PL emission.The best photoluminescence intensity was obtained for the 5%(molar fraction) cobalt doped ZnS quantum dots with MPA as the stabilizer.The cobalt doped ZnS quantum dots are 4 nm in diameter and are monodispersive.
