Recent advances in metal-organic frameworks for X-ray detection

Metal-organic frameworks(MOFs)are a class of fascinating supramolecular crystalline materials that have been widely developed for catalysis,gas storage,illumination,drug delivery/cytoprotection,and so on.Recently,MOFs have been found to have potential applications in X-ray detection due to their high sensitivity,fast response time,high absorption coefficient,and radiation stability.In this review,we present an overview on the fundamental mechanism of using MOFs for X-ray scintillation.We further discuss the recent developments in X-ray detection based on indirect X-ray scintillation and direct X-ray conversion.Finally,we provide a summary and a perspective on the future of this promising research field.
