Robust Radiative Cooling in Functionalizable Silica Microsphere Paints
Jorge Burgos, José Rodrigo Magana, Ares Lladós +5
Disordered coatings based on silica microspheres provide a scalable and robust platform for passive daytime radiative cooling. While particle-size optimization is often considered…
Surface Exciton Polaritons and Near-Zero Permittivity Surface Waves Supported by Artificial Organic Hyperbolic Metamaterials
José N. Gama, Diogo Cunha, Carla Estévez-Varela +11
Hyperbolic metamaterials enable extreme light confinement and control of photonic states, but their realization has been restricted to inorganic architectures. Here, a fully organi…
Room-Temperature Surface Exciton Polaritons in Colloidal J-Aggregate Flakes
Carla Estévez-Varela, José Nuno Gama, Miguel Castillo +6
J-aggregates are promising organic materials for nanophotonic applications due to their excitonic properties and ability to support surface exciton polaritons at room temperature,…
Bio-inspired polymers with polaritonic properties from visible to infrared: a material playground to mimic purple bacteria light-harvesting resonators
Samuel Thomas Holder, Carla Estévez-Varela, Isabel Pastoriza-Santos +3
Light-harvesting complexes in natural photosynthetic systems, such as those in purple bacteria, consist of photo-reactive chromophores embedded in densely packed "antenna" systems…
