摘要：
New fiber-optic carbon dioxide sensors utilizing a sensitive film containing an indicator dye on a polymer clad optical, fiber (PCF) are demonstrated. The sensitive film is a SiO2 gel film including an indicator dye of thymol blue or phenolphthalein, which is dip-coated by a sol-gel method. The attenuation of this sensor changes at the wavelength range of 500 to 700nm detecting CO2 gas.
