The invention discloses a cuprous complex orange yellow phosphorescence material in a crystal form based on diphosphine chelated ligand BINAP and 3-aminopyridine ligand and a preparation method thereof. A phosphorescence complex is obtained by complexing cuprous salt and ligand, and the molecular structure of the phosphorescence complex is shown as [Cu(BINAP)(3-apy)(CH3CN)](PF6), wherein BINAP isdiphosphine ligand 1, 1'-dinaphthalene-2, 2'-double diphenyl phosphine, 3-apy is nitrogen ligand 3-aminopyridine, and CH3CN is acetonitrile. The complex has the advantages that micromolecules are easyfor purification and luminescence efficiency is high and has high thermostability. The material is obtained through direct mixing reaction of Cu(CH3CN)4PF6 and a dichloromethane solution of the ligand, thereby having the advantages of simple and convenient process, simple equipment, easy-to-get raw materials and low cost. The material can serve as a photoluminescence orange yellow phosphorescencematerial and can be used a
