【Abstract】 A novel synthesis method of ZnS∶Cu aqueous colloid was studied, in which that the Cu + was induced to ZnS matrix by sulfurous ligands thoiurea and thiosulfate. ZnS∶Cu colloids were synthesized and the optical properties were studied by absorption spectra, emission spectra and excitation spectra. According to Brus Effective Mass Approximation, the average diameter of ZnS nanoparticles is about 4nm. Excited at about 320nm, a green emission band can be observed, which corresponds to luminescence from copper ions. Cu + should have entered the lattice of ZnS nanocrystals. Excitation spectra show that the emissions of ZnS∶Cu and ZnS colloid have the same luminescent mechanism. In the synthesis route, thiourea and thiosulfate act as ligands and surfactant simultaneously, and their functions can be summarized as Cu + stabilizing effect, solubility leveling effect and surface protecting effect.更多还原
