高灵敏NO_2气体光纤传感器

Highly-Sensitive NO_2 Optical Fiber Sensor

高灵敏NO2气体光纤传感器是基于方块菁染料的荧光强度在微量NO2气体中发生猝灭特性。通过实验得到SQ3块菁染料在不同NO2气体浓度下的荧光光谱特性。

The principle of the highly-sensitive NO2 fiber optical sensor is based on the phenomena that the fluorescence of squarylium dye can be quenched when exposed in low concentration of NO2. The characteristic of fluorescence spectrum of SQ3 squarylium dye exposed in various concentrations of NO2 are acquired through experiment.
