Metal-Organic Frameworks (MOFs) are hybrid organic-inorganic materials with enhanced electronic and optical functionalities that can be tailored by the judicious selection of the building units or their combinations. A large-scale diversity of metal-ligand combinations, along with the ability to form composites, have allowed MOFs to realize enhanced luminescence functionality with applicability in the avenues of solid-state lighting, luminescence-based sensors, and organic light emitting diodes (OLEDs). Because of their enhanced fluorescence lifetimes, high quantum efficiencies, and large-scale tunability, the luminescent MOFs and their composites hold great promise for the OLED industry with enhanced potential to resolve low efficiency issues. The present article presents a comprehensive review of emerging applications for luminescent MOFs and their composites in various OLED applications, with a focus on key attributes like quantum efficiencies, emission lifetimes, tunability, Commission internationale de l'éclairage (CIE) color coordinates, etc. At last, the prospects of luminescent MOFs have been addressed with respect to their future roles and applications in the OLED industry.
