Abstract: A radiative cooling composition comprises a first component having >55% reflectance in a wavelength range of 0.2 to 2.5 μm and a second component having >0.85 peak thermal emissivity for at least one wavelength in a range of 4-35 μm. A third pigmented component of the composition is configured to emit at least a fraction of absorbed energy, and in certain embodiments the pigmented component comprises at least one phosphor.
