Figure 3From: A turn-on fluorescent solid-sensor for Hg(II) detectionColorimetric changes in the Rh-UTES derivative solutions. (a) Before Hg2+ addition and after Rh-UTES-Hg2+ complex formation at the following molar ratios: (b) 1:1, (c) 1:6, and (d) 1:10, respectively. Rh-UTES concentration remained fixed at 1.16 μM in ACN solution.Back to article page
