Chemical sol–gel-based sensors for evaluation of environmental humidity

Crystal violet and chlorophenol red pH indicators were independently encapsulated into sol–gel matrices to be used as environmental humidity and acidity optical sensors, respectively. Absorption spectra of the prepared sensors were recorded before and after exposure under different controlled artifi...
