Thermal Emission Properties of Rare Earth Metals,
Abstract
The work functions of a number of rare earth metals have been calculated from data of experimental sputtering of rare earth metals of high purity onto a tungsten or rhenium substrate through an anode slit in a vacuum tube. The work functions appear to change uniformly, with the exception of divalent europium and, in the yttrium subgroup, lutetium. It is proposed that the total change in phi from lanthanum to lutetium is determined to a certain extent by the lanthanide compression. An additional factor is thought to be the reactions of free electrons with the f-shells, especially the resonance reactions.
