It is of great significance to explore new nonlinear optical (NLO) materials for the development modern laser testing technology. In this paper, two non-centrosymmetric organic-inorganic hybrid Pb-based bromides, (CH5N3S)2Pb5Br10 and (CH5N3S)Pb2Br4, were synthesized by a simple hydrothermal method.

Two organic–inorganic hybrid fluorooxoiodates, namely, (C 5 N 2 H 7 )IO F and 3 6 8 )(IO ) , were obtained. The parallel arrangements of the organic π conjugate cations produce a large birefringence in UV wave band.

Inorganic selenites are promising candidates for nonlinear optical and birefringent crystals. However, that can effectively transmit in the UV region still relatively scarce. In this study, we successfully synthesized first Zn-based selenite with properties using a hydrothermal method by introducing Zn2+ La3+ ions, which cause blue shift compound's bandgap, into system. The compound crystallizes chiral space group P3112 presents unique three-dimensional structure composed of two-dimensional zinc layers bridged LaO10 polyhedra. Notably, possesses wide bandgap (5.0 eV), high birefringence (0.092 at 546 nm), excellent thermal stability (∼540 °C), broad transparency window (0.21-6 μm), apparent SHG efficiency (0.2 × KDP). Our work not only demonstrates great potential as crystals but also expands research scope materials.
