Aerosol-generated sol-gel derived thin films and applications thereof

摘要

A sensor having a substrate overlayed with a sol-gel layer, a chemical sensing species deposited upon the sol-gel layer, and a thin film of a second sol-gel layer overlaying and entrapping the species. The effect of this sensor is that the species exhibits a significant portion of its intrinsic function over a period of time. In yet another embodiment of the subject invention, a method is disclosed to form a thin sol-gel layer upon an ambient substrat. This method ensures the integrity, stability and functionality of the chemical sensing species within the sol-gel layers.
