摘要：

Optical pH sensors based on different fluorescence decay times of acid and base forms of suitable indicators have been developed. The indicator is incorporated in a hydrogel matrix providing the aqueous environment necessary for the acid-base reactions. Dramatic improvement of long-term stability and reproducibility compared to conventional intensity-based sensors is obtained.
