The invention discloses a dye@metal organic framework (MOF) material for white light LED and an in-situ preparation method thereof. The dye@MOF material preparation method is as follows: 5,5'-(anthracene-9,10-diyl)diisophthalic acid (H 4 L), indium nitrate, red rhodamine B (RhB), Green light acridine flavin (AF) is synthesized by in situ one-step synthesis of dye@MOF composite rare earth-free white phosphor material through solvothermal reaction. The white light fluorescent powder provided by the invention has the advantages of simple preparation process, mild synthesis conditions, high yield and no rare earth elements, and the color temperature and color rendering index meet the lighting requirements. More importantly, the preparation method successfully solves the problem that the dye molecules are easily leaked from the loaded MOF host, resulting in weakened luminescence. |
