introductionpurpose ： enhance sensitivity and selectivity ， achieve the online monitoring of gas and chemical vapors

priciple ： the peak position or peak intensity of the resonant wavelength exhibits a respond upon exposure to chemical vapors

Advantage:(1) resistivity to electromagnetic noise and fire resistance2) the capability of remote control and information transfer through an optical fiber network, also miniaturized, convenient for on-site monitor3) facilitate the combination with imaging technology

Peak wavelength shift as a function of the concentration of six kinds of organic vapor with relative concentrations from 20% to 100% on the

PSi/IL(BmimPF6) and blank Psi sensing spots
