Abstract

The present work reports results of the electron paramagnetic resonance (EPR), optical absorption, radio- and photoluminescence (RL and PL) complex study of the Lu₂Si₂O₇:Pr and Lu₂Si₂O₇:Ce pyrosilicate crystals. In both crystals, the EPR spectra demonstrate the presence of characteristic signals originating from the Yb³⁺, Er³⁺, Nd³⁺, Dy³⁺, Gd³⁺ and V³⁺ ions existing in the material as uncontrolled impurities. The corresponding spectra (except for Gd³⁺) have been analysed in detail and g- and hyperfine tensors are determined for all these ions for the first time in the lutetium pyrosilicate lattice. Optical absorption, RL and PL measurements in the Lu₂Si₂O₇:Pr crystal have shown only the characteristic Pr³⁺ transitions. In addition, the Pr³⁺- Pr³⁺ energy transfer was observed and confirmed experimentally.
