Abstract
Using UV-absorption and fluorescent spectroscopy and photocolourimetric methods, a number of the colour acid-base indicators immobilized within nanoporous gassy matrix were investigated in respect to its spectral sensitivity to ambient atmosphere content. Obtained results open prospects of its application in developments of the optical gas sensors for the remote air monitoring systems.
