heal.abstract	NiCl/SiO2 sol gel materials are proposed for the first time for ammonia sensing. Thin films are prepared by spin coating or casting the solution on appropriate substrates and tested for sensitivity in ammonia environment. We report a uniform optical response over the visible spectrum in optical transmission. The main mechanism of operation is based on reversible physico-chemical complexation effects, which produce morphology alteration and result in enhanced optical scattering of the thin film material. Such ammonia sensor can find applications in industrial and environmental engineering fields including ""on-line"" process and quality control, environment monitoring and safety.	en
