中文摘要报道了一种基于荧光猝灭原理的光纤氧气传感器.采用塑料光纤作为传感和传光元件进行氧气传感,传感头制成U形.以邻菲咯啉钌作为荧光标记物,用溶胶-凝胶法制备敏感材料.采用相移法来实现对荧光寿命的测定.测量了不同弯曲半径传感头对氧气传感的灵敏度,发现当U形光纤的弯曲半径较小时系统的灵敏度较高.对荧光寿命和氧气浓度的关系进行了测量,发现二者呈亚线性关系,提出双荧光体模型解释这一实验现象.; A oxygen sensor based on fluorescence quenching is reported, plastic optical fiber as sensor head and light transmit element for oxygen sensor are adopted. The sensor head is made into U-shape. We use Dichlorotris (1,10-phenanthroline) ruthenium (II) as fluorescence indictor. Sol-gel method is used to prepare the sensor material. We detect the fluorescence lifetime by using phase modulation technique. The effect of bending radius on sensitivity is measured, and we find that the system sensitivity will increase when the curve radius decrease. We also measure the relationship between oxygen concentration and fluorescence lifetime, and find that they are sub-linearity. Double fluorescence site model is put forward to explain this phenomenon.
