Thermal radiation of Er doped dielectric crystals: Probing the range of applicability of the Kirchhoff’s law
Abstract Kirchhoff’s law of thermal radiation, relating emissivity and absorptance is commonly formulated for opaque bodies in thermodynamic equilibrium with the environment. However, in many systems of practical importance, both assumptions are often not satisfied. We revisit the century-old law an...
