In order to avoid the negative impact of heat treatment on the properties of materials prepared by the traditional wet chemical method, a simple and feasible process was proposed: a colloidal silver colloidal dispersion was prepared by colloidal chemistry, Using it as a source of nano-particles, the rhodamine 6G (R6G) molecule of organic dye was coated on the surface of the silver nano-particles, and the colloidal dispersion was uniformly doped into the gelatin solution to prepare dye-coated colloidal silver nano-particles Miscellaneous organic composite film. In this work, ternary composite films doped with inorganic and organic active elements were successfully prepared, and the idea of completely covering the metal nanoparticles by the dye molecules and the embedding process of the active elements at room temperature were achieved. The microstructure of the composite film was observed by electron microscope (TEM), and the UV Vis absorption spectrum of the composite film was measured. A cladding-doped structure model is given, and the model is used to successfully explain the experimental results
