摘      要：Nonlinear optical(NLO)crystals can be employed to expand the laser frequency and thus are of technical importance in advanced laser science.Noncentrosymmetric rare earth compounds keep attracting broad interest as a significant branch of NLO materials because the highly distorted structural motifs centered by rare earth ions could remarkably benefit the second harmonic generation.In this review,we proceed from structure-properties relationship and reveal the role of rare earth element in the optical properties of NLO materials.We believe that this work can deepen the understanding of rare earth-based NLO materials and provide some enlightenment for exploring novel practical NLO crystals.
