The invention discloses a yellow light emitting iridium phosphorescence coordination compound and a method for preparing the same. The yellow light emitting iridium phosphorescence coordination compound is structurally characterized in that 2, 4-(3, 5-dimethyl phenyl) bipyridine is used as a cyclometalated ligand, and acetylacetone, 2, 2, 6, 6-tetramethyl-3, 5-heptanedione or 2-picolinic acid are used as auxiliary ligands. The yellow light emitting iridium phosphorescence coordination compound and the method have the advantages that the emission wavelengths of three iridium phosphorescence coordination compounds are 565 nm, 575 nm and 550 nm respectively, and the iridium phosphorescence coordination compounds are yellow light emitting iridium phosphorescence coordination compounds prepared by the aid of the method.
