ENLIGHTMENT is an ERC Starting Grant (637116) granted by the European Union to Dr. Mihi and developed at the Institute of Materials Science of Barcelona – ICMAB - CSIC
Photonic and plasmonic architectures can concentrate the electric field through resonances, increase the light optical path by strong diffraction and exhibit many other interesting optical phenomena. The use of these structures within actual devices will be most beneficial for enhanced light absorption solar cells, photodetectors and improved new sensors and light emitters. However, emerging optoelectronic devices rely on large area and low cost fabrication routes to cut manufacturing costs and increase the production throughput. In our group we use the technique of soft nanoimprinting lithography, where a soft elastomeric pre-patterned stamp is used to mold unconventional materials such as conductive polymers, cellulose or metal colloids or perovskite nanocrystals. The resulting photonic architectures combine the photonic properties of the pattern with those of the original material resulting in a new generation of inexpensive photonic components such as biodegradable photonic films, highly efficient SERS platforms for sensing, improved efficiency solar cells and more.
Dr Mayte Gómez Castaño sucessfully defended her PhD thesis entitled Optical metamaterials: Design, up-scalable fabrication and characterization. Many congratulations photon!
Our recent work on assembled perovskite nanocrystals for amplified spontaneous emission graces the cover of Angewandte Chemie. The image illustrates the assembly process and the resulting photonic architecture after removing the patterned mold.
Our research about the High-throughput nanofabrication of metasurfaces with polarization dependent response has been published in Advanced Optical Materials. A great teamwork within the Enlightment group.
