Sol–Gel Chemistry has many advantages over other methodolo-gies to prepare materials, such as low temperature processing and shaping, higher sample homogeneity and purity, the easy tailoring of composition and properties (mechanical, hydrophobi-city, etc.), and the possibility to incorporate specific functions for particular purposes (organic functions, complexes, etc.).
Nevertheless, the term Sol-Gel has significantly evolved in the last few years, becoming a powerful tool to prepare multifunc-tional materials with excellent control of their structure at the mi-cro-to-nanoscale. From the pioneer works on sol-gel silica and hybrid organic-inorganic siloxane glasses, sol-gel strategies have been adopted in nanoscience and nanotechnology to de-velop mesoporous materials, nanostructured metal oxides, hal-ides or chalcogenides, semiconductor quantum dots, metal na-noparticles, etc.
This seminar will present several sol-gel strategies that we have applied to prepare luminescent nanocrystals with a good control on their nanostructure and properties. Some examples of functional metal oxides and metal halides, including up-converting systems and metal halide perovskites, will be presented. In addition, since working with nanopar-ticles is not always convenient for industrial applications, they can be embedded into bulky materials in order to translate the functional properties to the nanocomposites in a synergistic way. This strategy will be illustrated with some examples based on supramolecular organic gels, hybrid siloxane glasses and commercial polymers.
It is our pleasure to invite you to join the ISGS eSeminar for March 2023, which will be delivered by Associate Professor Beatriz Julián López on Monday 6 March. Beatriz is a member of the Board of Directors of the ISGS and will be familiar to members of the sol-gel community as co-organiser of the 7th ISGS Online Summer School (and of the 8th ISGS Summer School, to be held in October 2023).
