Emissivity is a measure of how effectively a material emits infrared radiation (heat) compared to an ideal "black body" that radiates perfectly at a given temperature. It's expressed as a number between 0 and 1, where 1 represents a perfect emitter and 0 represents a material that doesn't emit thermal radiation at all.
