Abstract
In2O3(Sn) film CO senors in the Kretschmann configuration were investigated using a rotating analyzer spectrometer. From the experimental surface plasmon resonance (SPR) angular dependencies, applying the best fit method complex dielectric permitivity of In2O3(Sn) films ((epsilon) equals 2.4-i0.2) were obtained. Under exposition of sensor by CO gas at 134 degrees Celsius temperature, SPR shifted to higher angles and sufficiently broadened. Most significant change possesses an imaginary part of dielectric permitivity -- after 0.8% CO exposition it becomes 4.1, whereas a real part equals to 1.2.
