【Abstract】 In this paper,we study the optical property of ZrO 2 thin film in alcohol and ammonia vapour,the film is made by sol gel method and it shows high sensitivity to alcohol and ammonia when adultrated by proper stabilizer,its light transmitancy increases monotonously as the gas concentration increased.The sensitive wavelength range extends to full visible spectrum.The property of the material shows that it is of great practical value for gas sensing fiber sensor.We also discussed the sensing mechanism in this paper.更多还原
