The V2 O5 doped ZnFe2 O4 solution as a sensitive reagent was prepared by sol-gel methods.And the V2 O5 doped ZnFe2 O4 solution was fabricated through the dip-pulling methods and was coated on to the surface of tin diffused glass optical waveguide,then we obtained the V2 O5 doped ZnFe2 O4 composited thin film/tin dif-fused optical waveguide sensor.After fabricating the sensor,we detected the sensing properties of the gases such as xylene,styrene to the film.The experimental results indicated that this sensor exhibited good sensitivi-ty、repeatability and selective response to xylene.The minimum concentration of detection to xylene of sensor was 1×10-6 .The sensor had high sensitivity,fast response,easily fabricated at room temperature and simple structure.
