Abstract
A methyl green/polyvinyl alcohol(PVA)sensing film is used to immobilize onto the surface of a potassium ion(K+)exchanged glass optical waveguide component by spin-coated method and an acetone optical sensor is successfully developed.The experimental results show that the sensor has good linear response to acetone vapor in the concentration range of 25
6
50 mg/m3 with a correlation coefficient of 0.991 15(n=5).The detection limit is estimated to be 11 mg/m3(S/N=3)and the response time is less than 3 s.The sensor has the characteristics of good reversibility
