Paper Abstract

A family of indicators has been developed for measuring different analytes, all the indicators being derivatives of the same chemical compound and having identical spectral and lifetime properties. The indicators show an absorption accessible to low-cost light sources, a large Stokes shift, and a long fluorescence decay time. All indicators can be excited at the same excitation wavelength, monitored at the same emission wavelength, and measured within the same time range. This opens the possibility for a compact lifetime-based instrument for water monitoring.
