摘要：

The correlation between photoluminescence in the near-IR region and point defect centers in the LiNbO3 crystals co-doped with Zn and Mg both by homogeneous and direct methods has been studied. X-ray diffraction (XRD) analysis shows that the LiNbO3:Zn:Mg (4.68:0.9 mol%) crystal obtained by homogeneous doping has the least number of intrinsic defects compared to the others. It has been established that ZnLi defects stimulate photoluminescence (PL) in the near-IR region of the luminescence spectrum in the LiNbO3:Zn:Mg crystals obtained by homogeneous doping. The LiNbO3:Zn:Mg (4.68:0.90 mol%) crystal has the maximum PL intensity and the LiNbO3:Zn:Mg (3.83:0.97 mol%) crystal has the minimum. Both crystals are doped homogeneously. Such defects as niobium vacancies (V-Nb) and niobium in the empty octahedron (Nb-oct) are suggested as luminescence quenchers in the co-doped crystals.
