Macromolecular Rapid Communications, Volume 46, Issue 3, February 2025.The figure showcases a daytime radiative cooling film that uses hollow yttrium oxide spheres within a polydimethylsiloxane matrix. This film reflects sunlight and emits long‐wave infrared radiation, effectively cooling the surface under direct sunlight. FDTD simulations confirm the scattering efficiency of the hollow spheres, highlighting their role in
