Hierarchical molecular design of high-performance infrared nonlinear Ag2HgI4 material by defect engineering strategy
TL;DR: In this paper, a hierarchical molecular design strategy was applied to synthesize a promising NLO material Ag2HgI4 by a simple solution method, which shows the strongest second harmonic generation (SHG) response in inorganic halides (4 × AgGaS2 (AGS)) and wide transparency range.

A Series of Organic-Inorganic Hybrid Compounds [(C2H5)4N]InCl4-xBrx (x = 0, 2, 4): Synthesis, Crystal Structure, and Nonlinear Optical Properties.
TL;DR: The relationship between halogen composition and band gap, optical anisotropy, and frequency doubling effects were evaluated by first-principles calculations, thus suggesting that halogen regulation favors the design of new organic-inorganic hybrid halides with excellent performances for many optoelectronic applications.

Nonlinear organic–inorganic halide hybrids containing unprecedented linear [MIX2]− coordination units and quasi-two-dimensional lone pairs
TL;DR: This work shows a first family of monovalent-metal-based hybrid halides [N(CH3)4]MCl2 (M = Ga, In) with a zero-dimensional configuration containing unprecedented linear [MX2] units, leading to a narrowed bandgap, enhanced optical anisotropy and strong nonlinear second harmonic response.
