摘要：

Site-selection spectroscopy techniques have been used to investigate the different Nd3+ crystal-field sites appearing in LiNbO3:Nd3+ and LiNbO3:Nd3+, Mg2+ crystals. Singly doped crystals show the presence of two nonequivalent sites for Nd3+ (here labelled as Nd-1 and Nd-2 sites). Codoping the crystals with Mg2+ ions induces the presence of a new Nd3+ site (labelled as Nd-Mg site) concomitant with fewer Nd-1 sites. These three crystal-field sites have been optically characterized by their highest-energy emission peak of the 4F3 --> 4I9/2 transitions. The possible location for these sites is the host matrix is discussed.
