Emission of optical radiation by the process of thermal radiation.
Thermal radiation is electromagnetic radiation originating in the thermal motions of particles of matter (atoms, molecules, ions, etc.). All matter above the temperature of absolute zero emits thermal radiation. Objects around room temperature emit mainly infrared radiation. Objects at temperatures higher than some 800 K also emit electromagnetic radiation in the visible area.
