Red luminescent material, preparation method and application thereof

The red luminescent material comprises inorganic particles, a silica skeleton and an organic solvent, the inorganic particles and the silica skeleton are connected through chemical bonds, the chemical component of the inorganic particles is a fluorine compound containing silicon and Mn < 4 + >, the silica skeleton comprises a monomer containing silicon and oxygen atoms, and the organic solvent is an organic solvent. Silicon and oxygen atoms are alternately connected to form a main chain and can be dissolved in an organic solvent to form a skeleton structure, and the red luminescent material is macroscopically represented as a gel state and does not have macroscopic fluidity; the red luminescent material is in a sol state after being diluted by the solvent and has fluidity; the red luminescent material is in a powder state after being dried, flowing sol-state ink can be formed by dispersing the red luminescent material in alcohols or other organic solvents, the effect that inorganic luminescent particles do no
