The 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 V3þ ions existing in the material as uncontrolled impurities. The corresponding spectra (except for Gd3þ) 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.
