Rational Design of a Niobium Tellurite Crystal Nb2Te3O11 Exhibiting Good Overall Infrared NLO Performance by Structural Genetic Engineering

“…This favorable arrangement facilitates the formation of acentric structural building units, leading to the crystallization of compounds in NCS space groups endowed with significant microscopic polarizability . Exemplary of this phenomenon are materials such as perovskite-structured KNbO 3 , tungsten-bronze-structured Pb 2 KNb 5 O 15 , NaBa 2 Nb 5 O 15 , and K 3 Li 2 Nb 5 O 15 . − Notably, recent investigations have demonstrated that the combination of two distinct classes of cations, Te 4+ and Nb 5+ , within one compound serves as an effective strategy to obtain materials exhibiting intriguing properties. Among these fascinating compounds are quaternary tellurates, including InNb­(TeO 4 ) 2 , LiTeNbO 5 , and Cd 2 Te 4 Nb 2 O 15 , which have showed good promise as potential IR NLO materials. − Nevertheless, the investigation of niobium tellurates featuring two ions exhibiting the SOJT effect has predominantly centered around quaternary compounds, whereas there has been a dearth of research on ternary compounds.…”
