Preparation method of gold nano-flowers
The invention discloses a preparation method of gold nano-flowers, and belongs to the technical field of inorganic nano-material preparation. The preparation method of the gold nano-flowers comprises the following steps of the step 1, preparing gold seeds; the step 2, preparing a gold nano-sphere colloidal solution; the step 3, preparing an Au@PbS core-shell heterogeneous nano-material aqueous solution; the step 4, preparing an Au/PbS/Au nano-structure solution; and the step 5, preparing the gold nano-flowers. The prepared gold nano-flowers have the advantages of being stable in structure, adjustable in number of petals, abundant in plasmon electromagnetic hot spot, excellent in surface enhanced Raman scattering performance and the like, and are expected to be applied to detection of pesticide residues and viruses..
