主　　题：spectra crystal luminescent 

摘      要：The luminescent properties of Er^(3+) ions in LiNbO_(3):Er and LiNbO_(3):Mg, Er crystals at room temperature have been investigated by the emission spectra and the selective excitation spectra. The energy transition processes of Er3+ luminescence have been analysed. It has been found that the luminescent intensity of Er^(3+) ions in the LiNbO_(3):Mg, Er crystal increased up to 7.8 times compared with that in the LiNbO_(3):Er crystal. The decrease of the defect centre (NbLi) concentration due to doping with Mg^(2+) ions plays a key role in this phenomenon.
