Significant boost of the stability and PLQYof CsPbBr₃ NCs by Cu-BTC MOF.

ABSTRACT: Developing stable perovskite nanocrystals (NCs) with enhancing luminescent properties holds great importance for future potential applications in optoelectronics. Here, we engaged perovskite NCs in Cu²⁺ ion-based metal-organic framework (MOF) Cu-BTC (BTC = 1,3,5-benzene tricarboxylate) by physical mixing of MOF with CsPbBr₃ NCs in toluene solution. MOF-protected perovskite NCs achieved high photoluminescence quantum yield 96.51% than pristine state CsPbBr₃ NCs (51.66%). Along with the improvement in optical properties, the long-term stability of CsPbBr₃ NCs in the solution phase also increases considerably upon loading in Cu-BTC MOF. Moreover, the changes in the luminescent intensity of the samples have been observed for 3 months in the solution.
