The invention discloses a preparative method for flower-shaped nanometer cadmium sulfide, comprising the steps as follows: precursor containing cadmium, precursor containing sulfur and chelon are resolved in water to prepare solution; the solution is heated, and cooled to room temperature after the reaction finishes, and centrifugalized; the settled matter produced byr centrifugalization is washed with water and ethanol, dried and acquired the flower-shaped nanometer cadmium sulfide. The method disclosed in the invention has the advantages of simple technique, low cost and easy popularization. |
