发光装置
摘要：
本发明提供了一种发光装置。该发光装置包括发光元件和光转化部分，光转化部分吸收发光元件发出的一次光并将其转换为更高波长的二次光，光转化部分含有发光材料，发光材料包括有机配合物，有机配合物是由四吡咯大环配体A、稀土离子Ln以及氘代或卤代的三脚架配体B组成。本申请的发光材料中的有机配合物的卟啉类配体具有很高的敏化效率(70％～100％)、外量子点效率和出光稳定性。该发光材料应用至发光装置中时，提高发光装置的发光效率和稳定性。另外，选用不同稀土离子或稀土离子组合可以实现发射峰位置、峰宽的可调可控，以改善其发光性能。
摘要（英）：

A light emitting device, comprising: a light emitting element and a light conversion portion; the light conversion portion absorbs primary light emitted from the light emitting element and converts the same into secondary light having a higher wavelength; the light conversion portion contains a light emitting material, the light emitting material comprising an organic complex, wherein the organic complex is composed of a tetrapyrrole macrocyclic ligand A, a rare earth ion Ln, and a deuterated or halogenated tripod ligand B. A porphyrin ligand of the organic complex in the light emitting material has high sensitization efficiency (70%-100%), external quantum dot efficiency, and light emitting stability. When the light emitting material is applied to the light emitting device, the light emitting efficiency and stability of the light emitting device are increased. In addition, the use of different rare earth ions or a combination of rare earth ions may achieve the adjustment and control of the emission peak position and peak width, thereby improving the light emitting performance thereof.
