Rational design via dual-site aliovalent substitution leads to an outstanding IR nonlinear optical material with well-balanced comprehensive properties

The acquisition of a non-centrosymmetric (NCS) structure and achieving a nice trade-off between a large energy gap ( E g > 3.5 eV) and a strong second-harmonic generation (SHG) response ( d eff > 1.0 × benchmark AgGaS 2 ) are two formidable challenges in the design and development of infrared...
