摘要：

Rare earth materials have been regarded as ‘industrial vitamin’ or ‘industrial monosodium glutamate’, which were widely applied in information, energy, transportation, environment, aerospace and the other fields. Due to the unique 4f shell electronic structure, the rare earth materials demonstrate the excellent physical property of the optical, electrical, magnetic and nuclear aspects, acting as the strategic resources in China. Notably, the rare earth materials with the outstanding fluorescence emission from ultraviolet light to infrared light region play an important role among all kinds of luminescent materials. Significantly, the rare earth luminous complexes expected to become high⁃performance electroluminescence materials with the characteristics of narrow luminescence peak, high luminescence stability, and adjustable light color, and so on, which are attributed to the novel photoluminescence mechanism of both parity inhibited 4f⁃4f transition and parity allowed 5d⁃4f transition. Furthermore, a summary of recent advances in organic light⁃emitting diodes (OLEDs) of organic rare earth complexes supplies an insight for rationally designing and optimizing the high⁃performant OLEDs. © 2023 Cailiao Daobaoshe/ Materials Review.
