Photoluminescence of composition chemosensor films based on structured mesoporous silica and photonic crystal structures

Optical structured composition chemosensor films were obtained based on photonic crystal matrices with monodisperse spherical silica particles (MSSP) 190 to 245 nm in size which were saturated with a nanosol of silica particles modified by fluorescein. As a result, the MSSP surface is covered with n...

More Information
Summary:Optical structured composition chemosensor films were obtained based on photonic crystal matrices with monodisperse spherical silica particles (MSSP) 190 to 245 nm in size which were saturated with a nanosol of silica particles modified by fluorescein. As a result, the MSSP surface is covered with nanofilms of mesoporous silica, which provides the photoluminescence (PL) of the material. The photonic crystal structure of the composition film amplifies PL in comparison with a mesoporous reference.
