The hybrid anion strategy has been illustrated to be an effective way to design and synthesize high-performance nonlinear optical (NLO) crystals. Herein, a new NLO-active oxytelluride with highly polarized [GeOTe3]...

Herein, a novel IR NLO oxytelluride Sr3Ge2O4Te3 was successfully designed and synthesized through “partially O-to-Te substitution” strategy. Compared with the parent oxide, Sr3Ge2O4Te3 not only successfully achieves a phase-matchability transition...
