Self-organisation of organosilicas: new approach for the nanostructuration of thin films and the photolithography
Résumé
Sol-gel glasses doped with org. chromophores have numerous applications such as dye-lasers, non-linear optical materials, biosensors, or luminescence solar collectors. However, the final efficiency of devices depends not only on the intrinsic phys.-chem. quality and response of the different charge carriers and light-emitting layers, but also on a carefully controlled deposition process. In this context, our research is focusing not only on the design of new silsesquioxane precursors and on the control of their supramol. aggregation properties but also on the development of a new hydrolysis-polycondensation process. Patents have been deposited and collaboration initiated with the start-up Atheor within the framework of Languedoc-Roussillon Incubation (LRI). The field of the markers is addressed in particular to develop traceability solns. for conditioning industries. This company will exploit our patents for the development of invisible tracers on glass.
