Dual-emission of Eu based metal-organic frameworks hybrids with carbon dots for ratiometric fluorescent detection of Cr(VI)

The ratiometric fluorescent detection of Cr(VI) has been designed based on Eu3+ functionalized metal-organic frameworks hybrids with carbon dots, the sensing mechanism of CDs@Eu-MOFs fluorescence sensor on the basis of the inner filter effect (IFE) could occur.117
