英文摘要	The spin-orbit interaction of the 5d electron needs to be taken into account to give the proper energy structure for the 4f(N-1)5d configuration on heavy lanthanide ions occupying a site with ligands forming an octahedron. This paper derives theoretical results fro the energy structure by treating the t(2) orbitals as quasi p orbitals an then using angular-momentum coupling techniques. An analytic expression for the electric dipole absorption line strengths between 4f(N) multiplets and 4f(N-1)5d states is given in terms of various angular-momentum quantum numbers and re-coupling coefficients. The result is then applied to interpret the excitation spectrum of Cs2NaYF6:Er3+. The high-spin and low-spin states of Cs2NaYF6:Er3+ are discussed in terms of the wavefunctions obtained by using the developed theoretical model.
