Summary: This study confirmed that the heteroanionic oxysulfide tetrahedron can achieve balanced performance in infrared nonlinear optical crystals, including strong second-harmonic generation (SHG) response, proper birefringence, and wide band gap. The anion-mixing strategy was applied to discover melilite oxysulfide as a promising IR-NLO material system. These compounds exhibited unbiased performances of proper birefringences, strong SHG responses with phase-matchable ability, wide band gaps, and large laser-induced damage thresholds. The structure tolerance of melilite offers the possibility to improve the SHG response by tuning the orbital composition and hybridization near band edges.

Summary: We report a new monoclinic compound CNPFC with a double-layered structure, which exhibits DUV transparency and a high laser induced damage threshold. By measuring the refractive index differences and performing theoretical calculations, we further understand the properties and structure of this compound. The different coordination environments and hydrogen bonding interactions of the Cd-centered polyhedra are responsible for the interesting structural relationships among the three related compounds.

Summary: We report a new Zintl phase thermoelectric material with a peak ZT value of 1.2 at 648 K and an average ZT value of 0.8 in the temperature range of 300-650 K, which outperforms all known InTe-based materials to date. The synergistic optimization of electronic property and phonon transport are achieved through the purification of grain boundary scattering and Ga-doping-induced weak phonon-electron coupling, resulting in enhanced carrier mobility and concentration, leading to a significantly increased power factor.

Summary: In this study, the thermoelectric properties of the new material KCu5Se3 were investigated, revealing high power factor and ultralow thermal conductivity. The complex crystal structure and weak chemical bonding of KCu5Se3 contribute to its low thermal conductivity through limiting phonon transport and introducing diffusive phonons. This understanding provides new insights into the design and synthesis of complex chalcogenide materials.

Summary: A near-room-temperature nonlinear optical (NLO) switch material, [Ag(NH3)(2)](2)SO4, is reported, which exhibits strong room-temperature second harmonic generation (SHG) intensity. The material undergoes a reversible phase transition from a noncentrosymmetric room-temperature phase to a centrosymmetric high-temperature phase, where both the anions and cations are highly disordered. The structural disorder hinders phonon propagation, reduces thermal conductivity, and weakens optical anisotropy and SHG.
