Keywords

ammonia sensor, evanescent wave spectroscopy, sol-gel

Abstract

The paper presents the results of investigation on the application of sol-gel technique to production of sensitive films. The sensitive films are made using silica SiO2 in which an indicator is bound. Bromocresol purple was applied as the indicator. The films produced are sensitive to ammonia.
