DOI: 10.1039/C4CC05508J, CommunicationYe Lu, Bing Yan
We report a new ratiometric fluorescent pH sensor based on postsynthetically modified nanoscale MOF-253. By a PSM, two types of Eu3+ with different characteristic excitation wavelengths are realized in MOF-253. The pH sensor requires no calibration because only one of the two types of Eu3+ is affected by the pH variation.
