4 March 2011Parametrization of intensity of inter-Stark f-f transition
A parametrization scheme for the intensities of electric dipole parity-forbidden inter-Stark f-f transitions is
proposed. This parametrization retains all the advantages of the widely used "approximate Judd-Ofelt theory" and at the
same time, it takes into account the Stark structure of the optical spectrum of impurity ion, and so it is also applicable to
the RE3+ ions (such as Ce3+ and Yb3+) with poor optical spectrum. Spectroscopic characteristics of YAG:Yb3 + crystal
due to inter-Stark transitions are calculated and quite satisfactory agreement with the experimental data is obtained.
