At present, the main goal of TC16 is to perform collaborative research focused around the development of nanostructured glass and coating starting from liquid solution or dispersion, in particular glass and glass-ceramics obtained from sol-gel, colloidal chemistry, nanostructured ink will be investigated. The main research topics are: Glass-ceramics for photonic and solar applications and Hybrid organic-inorganic glass for functional applications
Activities and plans
1. TC ACTIVITY
The TC16 members had 2 meetings in 2019: June 2019 in Boston, where we decided to change the name of the TC16 and nominated S. Ribeiro vice-chair; August 2019 in St. Petersbourg, where common points of activities between ISGS board and TC-16 were discussed.
– Meetings attended
ICACC 2019 – 43 International Conference and exposition on Advanced Ceramics and Composites 2019 27 January – 1 February, Daytona Beach (USA), “Optical gas sensors based on surface plasmon resonance” (A. Martucci, Invited speaker).
25th International Congress on Glass 2019 – Boston 4-9 June 2019 (USA), “Solution processed nanostrucutred materials for functional applications” (A. Martucci, Invited speaker) and “Sol-Gel modified upconversion nanoparticles. Energy and biomedicine applications.” (S. Ribeiro, Invited speaker)
– Collaborative research project
In the framework of the CTC-funded collaborative research project “Nanocrystalline sol-gel coatings for solar energy applications”, the sol–gel method was used to prepare multi-component films with a complex structure, including photonic bandgap multilayer architectures. In particular, the following coatings have been developed:
- Down- and up-converting coatings containing rare earths, which absorb in the visible and emit in the NIR (down-conversion) or vice-versa (up-conversion), have been developed for photovoltaic solar cell application.
- Solar-control coatings which can reflect the sun light. The studied sol-gel coatings were based on ZnO:Ga or ZnO:Ge.
In the framework of such project A. Martucci visited the IST lab (in Lisboa) in November 2019. In 2020 it is planned the visit of a PhD student from IST lab in Padova for 4 months for doing XRD, ellipsometry and SEM.
R.Almeida, L. Santos and A. Martuccci are editors of “Sol-gel derived optical and photonic materials” which will be published by Elsevier in 2020. A. Duran, S. Ribeiro and J. Xu are contributing with a chapter.

In 2020, TC16 plans to focuse its activity on 2 or 3 collaborative research projects with well defined objectives.
