Popis: This work reports the investigation of Zeolite 3A layers obtained by spin coating process at low temperature for registration alcohol vapor. Phase composition of Zeolite 3A layers was studied with the help of X-ray diffraction (XRD). Optical polarization properties and sensorics application of Zeolite 3A layers deposited onto different substrates were investigated by modulation polarimetry. Optical polarization properties were observed by measuring of angular characteristics of V-component of Stokes Vector. The influence of substrate materials for Zeolite 3A on amplitude parameter of angular characteristics of V-component of Stokes Vector was studied. The dielectric and conductor materials as Glass slide, Indium Tin Oxide nanofilm and Gold nanofilm were used. The highest amplitude value of V-component of Stokes Vector corresponds to the Zeolite layer on gold nanofilm. The response to ethanol vapor was registered for the Zeolite layer on gold nanofilm.
