This invention provides a fluorescent complex possessing excellent durability and luminous intensity, and a lighting system utilizing the same. The fluorescent complex comprises a rare earth ion and a β-diketone ligand. In the fluorescent complex, the β-diketone ligand comprises a β-diketone skeleton, a fluoroalkyl group, and an electron donative linking group for linking the β-diketone skeleton to the fluoroalkyl group. The fluorescent complex can be utilized in a lighting system. The rare earth ion is preferably a lanthanoid ion, particularly preferably a europium or terbium ion. When the β-diketone ligand further comprises an aromatic group, the luminous intensity can be further improved.
