Radiative cooling has proven to be a powerful strategy for sustainable thermal management. Nanophotonic structures enabling broadband reflection lead minimization of sunlight absorption, which brought nighttime-limited radiative into daytime applications. However, this in turn restricts the accessible colorization coolers white or neutral, consequently hindering their practical applications, particularly aesthetic purposes. With few exceptions, selective absorption at specific visible...
Abstract Chiral plasmonics has been actively pursued since pushing its light‐matter interaction to an unnaturally extreme regime. Recently, chirality‐encoded metal–insulator–metal (MIM) motifs have promised compelling advantages in advancing chiroptic responses, as they enable a capacitive coupling and resultant strong electric magnetic resonances. However, the deterministic control over chiral MIM working at visible regime is out of reach. Here, large‐area resonators are demonstrated using...
Radiative cooling has emerged as a promising materials-driven approach to enabling passive for terrestrial structures. The prevalent wavelength-selective, solar absorption-driven colorization strategies have hindered performances, especially during the daytime. In this study, we present structured fluids platform that can simultaneously achieve extremely low absorption across spectrum (≈3%) and preservation of omnidirectional, full-color characteristics. addition, it serves an ideal...
