Classification: CPC F | IPC F

Claim 14:
15. The radiative cooling structure of claim 13, wherein:
the ceramic IR-selectively emissive layer is a SiOxNy layer having a thickness of 1 μm to 5 μm for avoiding infrared emission outside the wavelength region;
the monolayer has a closely packed structure, in which the ceramic particles are closely packed, each ceramic particle being a SiO2 particle and having a particle size of 1 μm to 3 μm such that the monolayer enables avoid infrared emission outside the wavelength region thereby improving the cooling power of the radiative cooling structure; and
the ceramic bonding; layer is SiO2 layer having a thickness of 0.1 μm to 2 μm.
