摘要

In this paper, characteristic of volatile organic compounds (VOCs) optical fiber sensor with zeolite thin film-coated spherical end were investigated detailedly. The zeolite film and spherical end constituted an arc-shaped inline Fabry-Perot (F-P) cavity, and VOCs were measured by monitoring the wavelength shift of F-P interference which induced by the VOCs molecule adsorption of the zeolite film. The responses of the optical fiber sensor for monitoring isopropanol and formaldehyde were observed and especially observing the response of the optical fiber sensor in the mixed VOCs state. Experimental results show that the sensitivities of the optical fiber sensor for monitoring isopropanol and formaldehyde are 281.9 pm/ppm and 4.99 pm/ppm, respectively. The optical fiber sensor is more suitable for isopropanol measurement than formaldehyde. In the mixed VOCs state, the characteristic of the optical fiber sensor for isopropanol measurement is slightly changed when the air chamber is mixed with low concentration of formaldehyde, but the optical fiber sensor is still effective for isopropanol measurement.
