Design and evaluation of highly sensitive luminescent terbium sensor for hypochlorite in water
Source abstract
Abstract
A novel terbium 2-methyl-benzoimidazole-5-carboxylic acid complex was prepared and incorporated into silica matrix (tetraethoxysilane) using a mild sol–gel technique. We then successfully fabricated a terbium luminescent xerogel, which maintained intense green emission even in pure water. The emission was rapidly (~1 s) quenched by ClO− (detection limit 10−5 M) but not NO3 −, CH3COO−, F−, Cl−, Br−, I−, CO3 −, and OH−. The selectivity appears to be due to the high vibrational energy of ClO− as well as its strong oxidation capability.
