在这项工作中，具有高量子产率的镧系金属有机框架被用于生成白光发光二极管（wled）的荧光粉。这些荧光粉的荧光颜色可以通过这些配合物中Eu3+/Tb3+的比例和包封香豆素460染料含量的不同组合来调节。此外，通过将这些荧光粉涂覆在商用紫外LED芯片上，可以制造出wled的原型。
In this work, lanthanide metal–organic frameworks with high quantum yields are used to generate phosphors for white-light-emitting diodes (WLEDs). The fluorescent colour of these phosphors can be tuned by the different combinations of the ratio of Eu3+/Tb3+ and the content of encapsulated coumarin 460 dye in these complexes. Further, prototype WLEDs were fabricated by coating these phosphors on commercial ultraviolet LED chips.
