**Abstract:** The development of white light emitting diodes (WLEDs) holds grea<sup>t</sup> promise for replacing traditional lighting devices due to high efficiency, low energy consumption and long lifetime. Metalorganic frameworks (MOFs) with a wide range of luminescent behaviors are ideal candidates to produce white light emission in the phosphor-converted WLEDs. Encapsulation of emissive organic dyes is a simple way to obtain luminescent MOFs. In this review, we summarize the recent progress on the design and constructions of dye encapsulated luminescent MOFs phosphors. Different strategies are highlighted where white light emitting phosphors were obtained by combining fluorescent dyes with metal ions and linkers.
