Abstract: Intensity parametrization of the electric dipole transitions within 4f2 configuration of Pr3+ in SrAl12O19 are reported, in which the mixing of the 4f2 transitional states with the explicit 4f5d states is taken into account. A new set of phenomenological intensity parameters, Tkq, 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=-5.46×10-5, 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.
