Abstract
- We report a new ratiometric fluorescent pH sensor based on post- synthetically modified nanoscale MOF-253. Two types of Eu3+ with different characteristic excitation wavelength are realized in MOF-253 by a postsynthetic method (PSM). The pH sensor requires no calibration because only one of the two types of Eu3+ is affected by the pH variation. [ABSTRACT FROM AUTHOR]
