Luminescence spectra and crystal field calculation of Pr3+ ion in crystal LiYF4
Luminescence of LiYF4: Pr in the visible and near ultraviolet region is investigated. In the visible region, the emissions observed were attributed to intra-4f2 -configuration transitions. It has been shown that these transitions take place predominantly from 3 P0 level and non...

| description |
Luminescence of LiYF4: Pr in the visible and near ultraviolet region is investigated. In
the visible region, the emissions observed were attributed to intra-4f2
-configuration
transitions. It has been shown that these transitions take place predominantly from 3
P0 level
and nonradiative relaxation rate between 3
P0 and 1D2 is weak even at room temperature. The
emission and excitation bands observed in the ultraviolet region were assigned to 4f2
4f5d
interconfigurational transitions. The energy levels of Pr3
4f2
configuration are fitted by using
the crystal field method. The set of free-ion and crystal field parameters corresponding to the
best fits allow to reproduce satisfactorily the experimental spectra. |
