Abstract: 
A new set of Ln-MOF (lanthanide-metal-organic framework) thin films, known as Ln-SURMOFs (surface-supported MOFs), is fabricated with a layer-by-layer, in order to generate solid-state white-lighting devices. A three-component approach is carried out for a rational combination of red, green, and blue (RGB) emitting Eu3+, Tb3+, and Gd3+ containing layers in order to achieve white-light emission. The Ln-SURMOFs are fully characterized by powder X-ray diffraction, infrared reflection-absorption spectroscopy, scanning electron microscopy, and photoluminescence spectroscopy (excitation-emission and chromaticity determination according to Commission International de l'Eclairage, CIE). The devices show CIE x,y coordinates of almost ideal white light (0.331, 0.329), as well as a correlated color temperature of 5570 K. Besides, the temperature dependent performance of the RGB-SURMOFs is studied at room temperature and at 77 K.
