Abstract

Optical absorption and luminescence spectra of the Sm³⁺-doped fluorophosphate glasses 75NaPO₃- 24CaF₂-1SmF₃ and 75NaPO₃-24BaF₂-1SmF₃, the phosphate glass 75NaPO₃-24.5ZnO-0.5Sm₂O and the fluoride glass ZBLAN:Sm³⁺ have been recorded. The dipole strengths of the transitions in the absorption spectrum are parameterized in terms of three phenomenological Judd-Ofelt intensity parameters (Omega) _(lambda ) ((lambda) equals 2, 4 and 6). The determination of intensity parameters for Sm³⁺ has inherent difficulties due to very large number of energy levels lying close to each other. In this case, we can take advantage of the property that both the dipole strengths and the squared reduced matrix elements of overlapping transitions are additive. The relation between the spectral intensities and the glass composition is discussed.
