Abstract ： The luminescent properties of Er3+ ions in LiNbO3 :Er and LiNbO3 :Mg,Er crystals at room temperature were investigated by the emission spectra and the selective excitation spectra. The energy transition processes of Er3+ luminescence were analysed. It is found that the luminescent intensity of Er3+ ions in the LiNbO3 :Mg,Er crystal is increased up to 7.8 times compared with that in the LiNbO3 :Er crystal. Decrease of the defect center (NbLi ) concentration due to doping with Mg2+ ions plays a key role in this phenomenon.
