Abstract: This paper gives a review of the present scenarios of research related to super-cool heat radiative materials with a detailed summary of the four most common materials with interesting findings. Scientists and researchers have come forward to find ways to tackle climate change due to global warming. One of the approaches that researchers are taking is uncovering and experimenting with passive heat radiating materials that radiate most of its heat in the spectrum of atmospheric transparency window (8-13 μm). In general, every heated object radiates heat in the form of electromagnetic radiation. But due to the greenhouse gases in the atmosphere, the earth acts just like a giant greenhouse. As a result, most of the radiated heat from the earth gets trapped in its atmosphere, except for the longwave infrared radiation (IR) one. The atmosphere is transparent to this kind of radiation and hence scientists hope that using the cold outer space (3K) as a heat sink, the earth might still be able to radiate back the excess heat. The objectives, structures, and the results of these different emitters have been discussed in this review paper. These materials do have significant potential if used in a planned way.
