| Abstract: | A sensitive optical waveguide(OWG) sensor which can be used to detect volatile organic compounds(VOCs) was presented. The sensing device(element) was fabricated by means of the immobilization of polyvinyl pyrrolidone(PVP)-cyclodextrin(CD) composite film over a single-mode potassium ion exchanged glass OWG via spin-coating method. The sensor shows higher response to styrene gas than to other VOCs and displays a linear response to styrene gas in a range of 1-1000 μL/L. |
