| Abstract: | 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. |
