A fiber optic sensing method for monitoring sulfur dioxide(SO2)in environment is presented.With blue LED excitation source and miniature fiber optic spectrometer,the intensity of photoluminescence peak for n-type porous silicon stabilized by photochemical method in SO2 gas is measured.By analyzing the variation of intensity,the concentration of SO2 gas can be obtained.According to theories of semiconductor electrochemistry and solid state spectroscopy,the basic principle of n-type porous silicon's formation and its SO2 sensing are discussed respectively.The chemical constitute of stabilized porous silicon is studied by infrared spectroscopy,and its SO2 sensing performance is also evaluated.It is shown that the photoluminescence of stabilized n-type porous silicon can rapidly and reversibly quenched by SO2 gas,and the corresponding peak in quenching process is very stable.The result demonstrates the feasibility of the fiber optic sensing method for monitoring SO2 gas in environment.
