The invention discloses a 3,4,9,10-perylenetetracarboxylic-diimide-based cyclometalated iridium complex fluorescence-phosphorescence dual emission material and an application to regulate excited state luminescence through utilization of the solution concentration of the material. The cyclometalated iridium complex takes a 3,4,9,10-perylenetetracarboxylic diimide derivative as an auxiliary ligand and takes a phenyl pyridine derivative as a main ligand unit. Through introduction of triphenylamine, carbazole and Mi borane electron-donating/electron-withdrawing groups to phenyl pyridine, energy levels of the ligand and complex are regulated. The material in a low-concentration solution (10M) emits yellow fluorescence, and has a maximum emission peak of 520 nm. The material in a high-concentration solution (10M) emits near-infrared phosphorescence, and has a maximum emission peak of 740 nm. As far as we know, it is reported for the first time, the excited state luminescence of the cyclometalated iridium complex is regulated through utilization of the solution concentration.
