Paper Abstract

A dissolved oxygen sensor based on U-shape plastic optical fiber (POF) was described. Analyte-sensitive fluorophore are entrapped into ormosil film by using Sol-gel method. Phase modulation technique is used to measure fluorescence lifetime. The influence of oxygen indictor concentration, annealing time and U-shaped POF curve radius on the systems sensitivity is studied.
