Novel microporous and layered luminescent lanthanide silicates

abstract

Recent developments in the field of luminescent lanthanide silicates have been reviewed. Combining in a single material microporosity and optical properties may lead to new types of sensing devices. Optically active centers (lanthanide ions or molecules) may be introduced in the micropores or/and embedded in the materials framework. Layered lanthanide silicates also offer the potential for host-guest chemistry, affording efficient luminescent materials and allowing fine-tuning of properties. Preliminary work indicates that these new materials may be prepared, by hydrothermal methods, in the form of powders and films.
