Method for preparing Vanadate nanophosphor and the Vanadate nanophosphor prepared by the method

摘要

The present invention relates to a method for producing a phosphor vanadate series, more specifically, (a) yttrium compound and a metal compound acting as an activator; And providing the cation solution and the anion solution was dissolved in distilled water in each of the vanadium compound; (B) mixing with an organic solvent and a surfactant to the aqueous solution of the cation and anion a cation aqueous solution to obtain a clear inverse microemulsion; And forming an aqueous solution of anionic inverse microemulsions; (C) forming a nano fluorescent precursor to a hydrothermal reaction in an aqueous solution after mixing the cationic and anionic aqueous inverse microemulsion inverse microemulsion; And (D) relates to a process for the production of a vanadate-based phosphor comprising the steps of heat-treating the nano fluorescent material precursor. Method of producing a series vanadate phosphor of the present invention can provide a vanadate-based phosphor having excellent luminescence brightness and the nano-scale using a hydrothermal synthesis method for preparing a phosphor precursor. ;
