| 摘 要： | 基于荧光淬灭原理的光纤氧传感器一直是许多研究工作的重点。介绍了一种制作简单、成本低的光纤氧传感器制造方法。该方法基于荧光淬灭原理,在光纤末端涂覆荧光材料铂八乙基卟啉(PtOEP)实现的。传感器中荧光材料被395nm的紫光激发,并由Y形光纤引导,使用广州犀谱光电USB2000+光谱仪记录荧光的发光强度时序图。最后得到的PtOEP的( I 0/ I 100 )-1的值为0.78,即光纤氧传感器的灵敏度为0.78,而且,斯特恩-沃尔默(Stern-Volmer)图显示出很好的线性特性。从氧气到空气环境的响应时间为24 s,从空气环境到氧气的响应时间是5 s。结果表明,基于荧光淬灭原理的光纤氧传感器具有较高的灵敏度和更快的响应时间。

| Abstract: | Fiber optic oxygen sensors based on the principle of fluorescence quenching have always been the focus by many research works. A simple and low-cost method for manufacturing fiber optic oxygen sensor was introduced.Based on the principle of fluorescence quenching, this method was realized by the fluorescence material platinum octaethyl porphyrin (PtOEP) coated on the fiber end.In the sensor, the fluorescent material was excited by the violet light of 395 nm and guided by the Y-shaped optical fibers, and furthermore, the luminescence timing diagram of the fluorescence was recorded using a spectrometer USB2000+ of Xipu Optoelectronics.The value of PtOEP (I0/I100)-1 is 0.78, that is to say, the sensitinity of the sensor is 0.78, and the Stern-Volmer diagram shows good linearity characteristics, and the response time from the air environment to the oxygen is 5 s while the response time from oxygen to air environment is 24 s.These results show that the fiber optic oxygen sensor based on fluorescence quenching principle has higher sensitivity and faster response time. |
