THE OPTICAL SPECTRUM AND ZEEMAN EFFECT OF CAF2:EU(2+).
Abstract
New measurements of the Zeeman effect and of the fluorescent lifetime as a function of temperature of Eu(2+) in CaF2 are reported. Estimates of the theoretical parameters are made, and it is shown that neither these estimated values nor the magnetic splitting support those simplified models, used to explain the Faraday rotation, that neglect either the crystal field or the Coulomb interaction between the 5d and the (4f)(6) electrons. Evidence is given that the relative intensity of the Zeeman components in emission is dominated by 'spin-memory' effects rather than by thermalization between the Zeeman levels of the excited state.
