Abstract |
The paper presents both theoretical and experimental study of spectral properties of the lead and cadmium tungstate crystals doped with some rare earth (RE) ions (Pr3+, Sm3+, Dy3+, Eu3+). Optical and luminescence properties of these crystals were investigated in a wide temperature region at the different excitation and registration wave length. Analysis of the Stark levels structure allows us to do conclusion about existence of two type of the emission centers formed on a basis of the RE3+ ions arranged in the different positions of the PbWO4 and CdWO4 crystal lattices.
