高性能荧光猝灭式光纤氧传感器

摘要

A kind of fiber optic oxygen sensor based on fluorescencequenching has been fabricated by using Ru(phen)3Br2 as the indicator.The weak fluorescence of the sensor head has been detected by the phase lock amplifying technology.The sensor has high detecting precision,strong ability of disturbance resistance ,good reproducibility and stability.%用钌两价正离子(Ru2+)—邻菲咯啉配合物为指示剂，研制了一种基于荧光猝灭原理的光纤氧传感器。采用锁相放大技术，实现了对弱荧光信号的检测。该传感器具有较高的检测精度、较强的抗干扰能力、较好的重复性和稳定性。
