Analysis of the Ground Configuration of Tm(3+) in CaWO4.
Abstract
The energy levels of singlet D, singlet G, triplet F, and triplet H terms of Tm(3+) in CaWO4 were established by an analysis of the absorption and fluorescence spectra. The absorption lines used to establish most of the energy levels were recorded over the wavelength range from 2.5 micrometers to the band edge at about 0.3 micrometer with crystals with temperatures from 2 to 300K. Transitions to the levels of the triplet H(6) multiplet were observed in fluorescence. An energy level scheme was constructed by using electric dipole selection rules and by the aid of theoretical calculations. The calculations were made by diagonalizing a Hamiltonian that describes the free ion and the crystal field in a basis of states spanning the entire 4f(12) configuration.
