quantitykind:PlanckFunction
  a qudt:QuantityKind ;
  dcterms:description """In the ISO System of Quantities, the $\\textit{Planck function}$ is defined by the formula $Y = -G/T$,
    where $G$ is Gibbs energy and $T$ is thermodynamic temperature. It is a thermodynamic potential divided by temperature (a
    "free entropy"), expressed in joules per kelvin, and is the Gibbs-energy counterpart of the Massieu function $J = -A/T$. The
    same name is also widely used in radiometry for the spectral radiance $B(T)$ emitted by a black body, given by Planck's law;
    that is a different quantity, of a different dimension, and is covered by quantitykind:SpectralRadiance.
