The invention discloses a preparation method of a flexible and high-strength inorganic nano-mesh-vein structure light-emitting film, which is specifically implemented according to the following steps: Step 1, adding a rare earth compound and at least one non-rare earth metal salt into a solvent, and adding a catalyst, Stir, then add a phosphoric acid ester end-capping agent, and continue to stir until the mixture is uniform to prepare a uniform and stable precursor solution, the dynamic viscosity of the precursor solution is 0.1-5Pa s, and the conductivity is 5-80mS/m; Step 2, the The precursor solution prepared in step 1 is electrospun to obtain a precursor nanofiber membrane with mesh-like vein structure; in step 3, the precursor nanofiber membrane with mesh-like vein structure prepared in step 2 is calcined at high temperature in an air atmosphere to prepare a flexible nanofiber membrane. High-strength inorganic nano-mesh-vein structure luminescent film. The preparation method of the flexible and high-strength inorganic nano-mesh-vein structure light-emitting film of the present invention solves the problem of poor light-emitting performance existing in the prior art. |
