Abstract

AbstractWe herein report two asymmetric germanate crystals, KNbGe3O9and K3Nb3Ge2O13, with different structures and optical properties derived from divergent polymerized forms of GeO4and NbO6groups. Remarkably, K3Nb3Ge2O13achieved a rare combination of the strongest second harmonic generation (SHG) response of 17.5×KDP @ 1064 nm and the largest birefringence of 0.196 @ 546 nm in germanates. It features unique [Nb3O12]∞tubular chains constructed by circular Nb3O15tripolymers. Theoretical calculations reveal that thed‐pinteractions in the Nb3O15group are responsible for outstanding optical properties. This work emphasizes the significance of the polymerizable functional units in obtaining high‐performance nonlinear optical (NLO) crystals.
