Intensity parametrization of 4f²→4f² electric-dipole transition in SrAl₁₂O₁₉:Pr³⁺

Intensity parametrization of the electric dipole transitions within 4f² configuration of Pr³⁺ in SrAl₁₂O₁₉ are reported, in which the mixing of the 4f transitional states with the explicit 4f5d states is taken into account. A new set of phenomenological intensity parameters, T_kq, are put forward, which are obtained from a best fit of the calculated and measured relative intensities of transitions from the ³P₀ level to the lower J multiplets. The fitted values, T₃₃ = 3.26 × 10^-5 and T₅₃ = -5.46 × l0^-5, have been used to analyze the transitions originating from the ¹S₀ level. The present results are compared with that of the Judd-Ofelt analysis and the experimental measurements.
